LED Running Lights Circuit: This is a simple circuit consists of 9 LED lights in knight rider scanner mode. It will present an eye catching look as the LED initially travel in the one way and then travel reverse in the similar direction.

62

Basic Logic Gates Using NAND Gate: We are all well known that NOT, AND, OR are the basic logic gates. Here we have shown how to design these basic logic gates using one of the universal gates - NAND Gate.

63

Construction of Basic Logic Gates using NOR Gate: Here, we have shown how to construct the basic logic gates - NOT, AND, OR gates using NOR Gate which is one of the universal gates.

64

Electronic Letter Box: This is a simple circuit which helps in finding out any letter dropped in our box by stopping the LED lights attached in this circuit.

65

Luggage Security Alarm: This is a simple alarm circuit which helps in ringing a warning alarm when someone tries to steal the luggage.

66

9 Way Clap Switch Circuit: This circuit helps you to manage your appliances in your home by just clap without moving from your bed.

67

Clap Switch Circuit for Devices: This is another simple but very useful circuit which helps to ON or OFF a device without moving from you place and also helps to control the speed of the electric devices like fan, etc.

68

Audio Equalizer Circuit: The circuit is used to change the tune/melody into a different pitch level by devoid of loss in the tune. It is mainly useful to music lovers.

69

12V to 24V DC Converter Circuit: This is another kind of circuit which helps to convert 12V DC current to 24V DC current.

70

Police Siren Circuit using NE555 Timer: This circuit produces a sound similar to the police siren. You may also get detailed information about pin diagram and internal block diagram of NE555 timer.

71

Mosquito Repellent Circuit: Here is the simple electronic mosquito repellent circuit which can produce ultrasound in the frequency range of 20-38 kHz, which can scare away mosquitoes.

72

Cell Phone Detector: This is a simple circuit which helps to detect the presence of an activated cell phone by detecting the signals in the frequency range of 0.9 to 3GHz. It helps in mobile phones tracking which are used for spying.

73

Air Flow Detector Circuit: This Air flow detector circuit can be used to detect the flow of air in areas like car engine. It can also be used as temperature detector.

74

12v DC to 220v AC Converter Circuit: Here is a simple voltage driven inverter circuit which converts 12v DC signal to single phase 220v AC using power transistors as switching device.

75

FM Transmitter Circuit: Here we built a wireless FM transmitter which uses RF communication to transmit the medium or low power FM signal. The maximum range of transmission is around 2 km.

76

150W Power Amplifier Circuit: Here we designed a power amplifier circuit using push pull class AB configuration to derive a power of 150W to drive a load of 8 Ohms (speaker).

77

100W MOSFET Power Amplifier Circuit: A power amplifier circuit using MOSFET has been designed to produce 100W output to drive a load of about 8 Ohms.

78

7 Segment LED Display Decoder: This is the circuit diagram of display decoder which is used to convert a BCD or binary code into a 7 segment code used to operate a 7 segment LED display.

79

100w Subwoofer Amplifier Circuit: Here is the circuit diagram and working of 100w subwoofer amplifier circuit. A Subwoofer is a loudspeaker which produces audio signals of low frequencies.

80

Password Based Door Lock System using 8051 Microcontroller: This system demonstrates a password based door lock system wherein once the correct code or password is entered, the door is opened and the concerned person is allowed access to the secured area. After some time, the door would be closed. Read this post completely to get more information.

81

Digital Tachometer using 8051 Microcontroller: Here we designed a simple non contact tachometer using microcontroller which can measure speed with an accuracy of 1 rev/sec.

82

Digital Voltmeter Circuit using ICL7107: Here we designed a analog to digital converter working as a digital voltmeter using a low power three and half digit A/D converter ICL7107 having internal 7 segment decoders, display drivers, a reference and a clock.

83

8 Channel Quiz Buzzer Circuit using Microcontroller: We built the circuit using a microcontroller which scans the input from push buttons and displays the corresponding number on a display device.

84

5 Channel IR Remote Control System using Microcontroller: This article is aimed to design and demonstrate a simple 5 channel remote control system to drive five loads. This circuit works on the principle of IR communication.

85

Battery Charger Circuit: This battery charger circuit works on the principle of controlling switching of an SCR based on charging and discharging of battery.

86

Bidirectional Visitor Counter using 8051: This Bidrectional Visitor Counter Circuit is helpful to count the number of persons entering or leaving a room and to display it on a screen.

87

Celsius Scale Thermometer using AT89C51: This Celsius Scale Thermometer circuit is designed using at89c51 and lm35. This circuit works on analog to digital conversion principle. It can be used at homes, mobile places like cars to keep a track of the temperature.

88

Bipolar LED Driver Circuit: This bipolar LED driver circuit is very useful at the places where flashing of light is required, as in beacon flashing. This circuit can be mainly used for indication purposes.
