Heart Shaped Serial LED Flasher using 4017 and 555 IC

This circuit uses the 555 IC and 4017 IC to flash the LED's one by one placed in shape of a Heart shaped , hence named LED flasher circuit. The 4017 is a decade counter which flashes the LED's one by one depending upon the clock signal received by it , here 555 produces clock signal and thus drives the 4017 IC to produce output at its pins. The output LED's can be easily connected in a Heart Shape in order to Make a nice flashing Heart effect.This...

Reaction Timer Game with 7 Segment

This is a game for two players. Player 1 presses the START button. This resets the 4026 counter chip and starts the 555 oscillator. The 555 produces 10 pulses per second and these are counted by the 4026 chip and displayed on the 7-Segment display. The second player is required to press the STOP button. This freezes the display by activating the Clock Inhibit line of the 4026 (pin 2). Two time-delay circuits are included. The first activates the...

Electronic Cricket Match Game using 555 IC and Decade Counter 4017

The Electronic Cricket Match game is presented below, the circuit has 8 LED which represent  various states in a cricket game - 2 runs ,six ,bowled etc. When the Push Switch S1 is pressed momentarily, the Astable operates and all the LEDs run very fast sequentially. When S1 is released, any one of the LED stands lit which indicates the status of the match. For example, if LED D7 remains lit, it indicates Sixer and if LED 8 remains lit,...

555 IC Tester Circuit

This simple 555 IC testing-circuit tests your entire 555 timer IC, so before using your IC check immediately that your IC is good or bad by checking it. This can be done by checking the IC that is it is oscillating or not. Or you can use this circuit in some other circuits also to troubleshoot the proper working of 555 IC. First of all insert the IC in socket very carefully so that no pin of 555 timer get damage. Now to see the result, switch...

Voltage Doubler Circuit using 555 IC

A voltage higher than the supply can be created by a "Charge-Pump" circuit created with a 555, diodes and capacitors as shown in the following circuit. The output will deliver about 50mA. This can be used for those components which require around 12v and the supply you have is around 5-6v , thus this is a very handy circuit for electronics DIY projects. COMPONENTS USED : 1.one 555 IC 2.one 1nF ceramic capacitor 3.one 100nF ceramic capacitor 4.one...
