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.

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 word array and thus letter 'W' is illuminated. Teks huruf berjalan sederhana 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 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 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 to make an fashion jewelery of any design. With two circuits connected in a similar fashion, multiplexing of 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.

Rangkaian 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. Function of each pin:. Ground, is the input pin of the negative DC voltage source. Trigger, the lower the negative input comparator (comparator B) that maintain low voltage oscillation capacitor in third Fcc and set RS flip-flop. Output, the output pin of the IC 555.

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. 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. 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. 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. 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. 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.
