Skema Rangkaian Alarm Mobil

This FM radio-controlled anti- theft alarm can be used with any vehicle having 6- to 12-volt DC supply system. The mini VHF, FM transmitter is fitted in the vehicle at night when it is parked in the car porch or car park.

The receiver unit with CXA1019, a single IC-based FM radio module, which is freely available in the market at reasonable rate, is kept inside. Receiver is tuned to the transmitter's frequency. When the transmitter is on and the signals are being received by FM radio receiver, no hissing noise is available at the output of receiver. Thus transistor T2 (BC548) does not conduct. This results in the relay driver transistor T3 getting its forward base bias via 10k resistor R5 and the relay gets energised.

When an intruder tries to drive the car and takes it a few metres away from the car porch, the radio link between the car (transmitter) and alarm (receiver) is broken. As a result FM radio module gene-rates hissing noise. Hissing AC signals are coupled to relay switching circ- uit via audio transformer. These AC signals are rectified and filtered by diode D1 and capacitor C8, and the resulting positive DC voltage provides a forward bias to transistor T2. Thus transistor T2 conducts, and it pulls the base of relay driver transistor T3 to ground level. The relay thus gets de-activated and the alarm connected via N/C contacts of relay is switched on.

If, by chance, the intruder finds out about the wireless alarm and disconnects the transmitter from battery, still remote alarm remains activated because in the absence of signal, the receiver continues to produce hissing noise at its output. So the burglar alarm is fool-proof and highly reliable.

3. SAKLAR OTOMATIS POMPA AIR
Seringkali air di penampungan di rumah kita selalu tumpah saat penampungan penuh.Lebih parah lagi kita lupa dan ditinggal begitu aja,alhasil air tumpah kemana-kemana.Saya pernah mengalami sampai air sumur saya habis,maklum saya tinggal diperumahan yang sumurnya asal ada,perumahan sekarang ya....gitu dech........
Sampai akhirnya saya memutar otak (asal jangan kepala kepala ikut muter) membuat alat pendeteksi tinggi rendahnya air.Inilah gambar rangkaian dan cara kerjanya :










Daftar komponen :
R1 = 100K C1,2 = 47n
R2 = 5K6 C3 = 220mf/25v
R3 = 680 Tr1,2,4,7,8 = FCS9012
R4 = 10 Tr3,5,6 = FCS9013
R5 = 1K D1-5 = IN4002
R6 = 270 Trafo 12v 350ma
R7 = 47K ab = PLN
R8 = 47K cd = Pompa Air
R9 = 100K
Relay = 12v DC
ABC = sensor (dari besi, stainlis atau lainnya)

C1,2 = 47n
C3 = 220mf/25v
Tr1,2,4,7,8 = FCS9012
Tr3,5,6 = FCS9013
D1-5 = IN4002
Trafo 12v 350ma
ab = PLN (input 220v AC)
cd = Pompa air

Cara kerja :
Misalkan kita menghendaki tinggi air dalam tangki tidak lebih tinggi dari titik A dan tidak lebih rendah dari titik B pompa air akan hidup sendiri dan bila menyentuh titik A pompa akan mati.

A=batas atas permukaan air yang dikehendaki
B=batas bawah air yang dikendaki
C=adalah kawat/kabel yang harus selalu menyentuh air di tempelkan ke badan tangki(kalu logam)

Akhirnya tangki air ga tumapah lagi.......

18. RANGKAIAN LED/HURUF

This is a running message display circuit wherein the letters formed by the LED arrangement light up progressively. Once all the letters of the message have been lit up, the circuit gets reset.

The circuit is built CD4017BC counter menggukan decades. One of the CD4017BE's features is its provision of ten fully Decoded outputs, making the IC ideal for use in a whole range of sequencing operations. In the circuit only one of the outputs remains high and the other outputs switch to high state successively on the arrival of each clock pulse. The timer NE555 is wired as a 1HZ astable multivibrator which clocks the IC2 for sequencing operations. On reset, output pin 3 goes high and drives transistor T7 to 'on' state. The output of transistor T7 is connected to letter 'W' of the LED word array and thus letter 'W' is illuminated.

On arrival of first clock pulse, pin 3 goes low and pin 2 goes high. Transistors T6 Conducts and letter 'E' lights up. The preceding letter 'W' also remains lighted because of forward biasing of transistor T7 via diode D21. In a similar fashion, on the arrival of each successive pulse, the other letters of the display are also illuminated and finally the complete word becomes visible.

On the following clock pulse, pin 6 goes to logic 1 and resets the circuit, and the sequence repeats itself. The frequency of sequencing operations is control led with the help of potmeter VR1. The display can be fixed on a veroboard of suitable size and connected to ground of a common supply (of 6V to 9V) while the anodes of LEDs are to be connected to emitters of transistors T1 through T7 as shown in the circuit. The above circuit is very versatile and can be wired with a large number of LEDsto make an LED fashion jewelery of any design. With two circuits connected in a similar fashion, multiplexing of LEDs can be done to give a moving display effect

If you think that 'there is a problem in the of availability of the chips mentioned in the schematic, then you cans use AT89C51/AT89C52 Also, make sure That you are using the Same port for the LCD and switches Which are there in the C- files or in the schematic.

in the image above as you cans see the digits are Bigger than the normal size. For this purpose I'm maiking use of the CGRAM of the LCD, Which gives to the user the flexibility to define user defined characters. so to create a character We first need to get the Which values are to be written into the CGRAM area. The CGRAM area starts from address 0x40 and for Every character Which there are eight locations are to be written.

Figure below shows the custom character creation. so Pls We get the values for all the pixels. These values We write to the CGRAM. The Digits 0-9 Can be created with the help of eight custom characters and Standard and Poor.
user defined character.


20. UM3561 - Simple Sound Effects Generator Circuit.

This is a very simple. The IC UM3561 produces four differen sound effects, the output at Pin 3 being amplified by the transistor 2N2222. A 64 ohm loudspeaker can be substituted in place of the 56 ohm resistor and 8 ohm loudspeaker.

The 2 pole 4 way switch controls the sound effects. Position 1 (as drawn) being a Police siren, position 2 is a fire engine sound, 3 is an ambulance and position 4 is a machine gun effect.
21. Rangkaian Motorcycle Alarm
This circuit features an intermittent siren output and automatic reset. It can be operated manually using a key-switch or a hidden switch; but it can also be wired to set itself automatically when you turn-off the ignition. By adding external relays you can immobilize the bike, flash the lights etc. I have used Andy's Asymmetric Timer as the basis for this design.
Rangkaian Motorcycle AlarmSkema Rangkaian IC 555 Motorcycle Alarm
Any number of normally-open switches may be used. Fit "tilt" switches that close when the steering is moved or when the bike is lifted off its side-stand or pushed forward off its centre-stand. Use micro-switches to protect removable panels and the lids of panniers etc.
The alarm's standby current is virtually zero - so it won't drain your battery. Once activated - the rate at which the siren switches on and off is controlled by R7, R8 & C4. For example, increasing R7 will make the sound period longer - while increasing R8 gives longer silent periods.
The circuit is designed to use an electronic Siren drawing 300 to 400mA. It's not usually a good idea to use the bike's own Horn because it can be easily located and disconnected. However - if you choose to use the Horn - remember that the alarm relay is too small to carry the necessary current. Connect the coil of a suitably rated relay to the "Siren" output. This can then be used to sound the Horn, flash the lights etc.
The circuit board and switches must be protected from the elements. Dampness or condensation will cause malfunction. Connect a 1-amp in-line fuse AS CLOSE AS POSSIBLE to your power source. This is VERY IMPORTANT. The fuse is there to protect the wiring - not the alarm. Exactly how the system is fitted will depend on the make of your particular machine - so I'm unable to provide any further help or advice in this regard.
When you set the alarm - if one of the switches is closed - the siren will sound. This could cause annoyance late at night. A small modification will allow you to Monitor The State Of The Switches using LEDs. When the LEDs are all off - the switches are all open - and it's safe to turn the alarm on

22. ALARM Sirine Berbasis SCR
This is a simple SCR based burglar alarm circuit. Its features include automatic Exit and Entry delays - together with a timed Bell cut-off and Reset. It's designed to be used with the usual types of normally-closed input devices such as - magnetic-reed contacts - micro switches - foil tape - and PIRs.
rangkaian alarm|sirineSkema rangkaian alarm|sirine
SCR-based alarm circuit is It's easy to use. When you switch on the alarm - you have about 30 seconds to leave the building. When you return and open the door - the Buzzer will sound. You have about 30 seconds to switch off the alarm. If you fail to do so - the Siren will sound.
After about 10 minutes - the alarm will attempt to reset itself. If the trigger circuit has been restored - the attempt will be successful. But - if the loop is still open - the attempt will fail - and the alarm will re-activate. Of course - you can turn the Siren off at any time by switching off the alarm.
A conventional bell uses up to about 400mA. An electronic siren generally uses less. If you intend to draw a heavier current from either the Buzzer or Siren terminals - the SCR in question will need to be bolted to a metal heatsink - and the relay contacts may need upgrading.
If you do not want the timed "cut-off and reset" feature - leave out D5, D6, R11, R12, Q3, Q4, C6 and the relay.
23. Alarm|Sensor Cahaya
This circuit is a loud alarm at the break of the daylight. The 555 timer IC is Used here. It is working as an astable multivibrator at a frequency of about 1kHz. This circuit can be used as an anti-burglar alarm in certain rooms, such as cupboard, cupboard in the open when the light will hit the circuit, so the alarm will be activated
Rangkain Alarm CahayaRangkaian Alarm|Sensor Cahaya
When no light falls on the LDR, the transistor is pulled high by the variable resistor. Hence the transistor is OFF and the reset pin of the 555 is pulled low. Due the this the 555 is reset. When light falls on the LDR, its resistance decreases and pulls the bases of the transistor low hence turning it ON. This pulls the reset pin 4 of the 555 high and hence enables the 555 oscillator and a sound is Produced by the speakers. The 100K variable resistor has to be adjusted to set the light intensity That triggers the alarm.

IC 555 Pinning
function of each pin:
  1. Ground, is the input pin of the negative DC voltage source
  2. Trigger, the lower the negative input comparator (comparator B) that maintain low voltage oscillation capacitor in third Fcc and set RS flip-flop
  3. Output, the output pin of the IC 555.
  4. Reset, the pin which serves to reset the latch inside the IC which will affect the work to reset IC. This pin is connected to a PNP-type transistor gate, so the transistor will be active if given a logic low. Normally this pin is connected directly to avoid reset Fcc
  5. Control Voltage, this pin serves to regulate the stability of the negative reference voltage input (comparator A). This pin can be left hanging, but to ensure the stability of the reference comparator A, usually associated with the order of about 10nF capacitor to pin groun
  6. Threshold, this pin is connected to the positive input (comparator A) which will reset the RS flip-flop when the voltage on the capacitor started to exceed 2 / 3 Vc
  7. Discharge, this pin is connected to an open collector transistor Q1 is connected to ground emitternya. Switching transistor serves to clamp the corresponding node to ground at a certain timing
  8. VCC, this pin to receive a DC voltage supply. Usually will work optimally if given a 5-15V. the current supply can be viewed in a datasheet, which is around 10-15mA.
24. Alarm Kebakaran
This is a simple fire alarm circuit, which can help the user's color interested against fire accidents based on a LDR and lamp pairs an alarm for sensing the fire.The works by sensing the smoke Produced During fire.The circuit produces an audible alarm the fire breaks Pls out with smoke.
Rangkaian Alarm KebakaranSkema Rangkaian Alarm Kebakaran
When a number of smoke passes Between a bulb and an LDR, the amount of light falling on the LDR decreases. This Causes the resistance of the LDR to Increase and the voltage at the base of the transistor is pulled high due to Which the supply to the COB (chip-on-board) is completed. Different cobs are available in the market to generate Different Musical. The choice of the COB depends on the user. The signal generated by COB is amplified by an audio amplifier. In this circuit, the audio power amplifier is wired around TDA2002. The sensitivity of the circuit depends on the distance Between bulb and LDR as well as the setting of preset VR1. Thus by placing the bulb and the LDR at appropriate distances, one May Vary preset VR1 to get optimum sensitivity. An ON / OFF switch is suggested to turn the circuit on and off as Desirable.

26.Inverter 12VDC to 220V 50Hz 500W 

 Rangkaian Inverter 12V DC ke 220V AC 500W.
Merangkainya cukup mudah dan harganyapun murah.

Friends favorite circuit about the the inverter, because like working outdoors, or to backup storage to use when necessary.
Most of this is circuit low power, which is not suitable for practical applications. My friends said that he would be about 500 Watt.
It is a good size. Use with television receivers and light bulbs as well.
When looking for circuit. I get headaches. If you are a beginner or I can not buy expensive good quality circuits. Requires only one transistor. Or if you have free time. I want to build old circuit is alive again. This circuit will accommodate all your needs. It is a simple circuit. The same principle, I take battery voltage 12V to produce a oscillator about 100 Hz and pass to a two frequency divider circuit is only 50HZ. And drive a 10 ampere transformer with 10 x 2N3055 transistor in parallel. By a single transistor has 2A, when I use 10 transistors or 5 pairs of drive high current output. The complexity of circuit, but the principle is not it, and it is the number of transistors on a basic, easy to buy.
