Electronic Dice - The 555 timer IC is connected for Astable Operation, the clock pulses are fed to the 4017 IC via the 10K resistor. The 4017 is a 10 stage counter, output 6 (pin 5) is connected to RESET (pin 15) , thus giving us a 6 stage counter , outputs 0 to 5.6 of the LEDs are connected as 3 pairs, thus requiring 4 different signals, these signals come from the 4 transistors, which in turn __ Designed by Andy Clarkson
Electronic Dice
- This circuit simulates a dice being thrown. Pressing the
button "throws" the dice. One of six LEDs will light up after
the throw. __ Starting Electronics Tutorial
Electronic Dice - I built this small Dice because we had a spare corner of PCB un-used of a larger PCB design. Project originally belong to Pete Griffiths and I thank his efforts in making such a nice project and make available code for free use. __ Designed by Nina Gajjar

Electronic NiCad gLow plug driver - Basically, it's a constant voltage source. It measures the voltage drop across the plug and adjusts its output to to keep that voltage constant (regardless of the resistance of the plug or the length of the wires). Therefore, when the engine floods, more power is delivered to help burn off the flood. __ Designed by Steve Sacco
Electronic quiz table - This is a circuit for a low cost electronic quiz table that can be used for four participants. Whenever someone presses a button first an alarm sounds and the person's corresponding bulb lights up and the other three are locked. __ Electronics for You

Electronics Cricket on board - This is very interesting project not for only who love cricket for also who love to watch this game because thousand of us want to play this game but some time it is not possible because of this busy life, lack of ground etc. The game electronics cricket on board can be played by anyone even in their home by sitting on table. The interesting fact is even a single player can play this game. __
Electronics Lucky Number - The circuit is simple and self explanatory. IC1, a NE555 timer, is used as astable mode to generate clock pulses at a rate of about 20 Hz. The frequency can be varied with the help of potentiometer VR1. __

Fake Joystick - The following very simple circuit can be used to make the computer to think that there is a real joystick connected to joystick port. This adapter might be useful in some special computer testing applications when you don't have real joystick available __ Designed by Tomi Engdahl
Fastest Finger First - This project describes a "Fastest Finger First" system that is cheap to build, has high noise immunity, is reliable and is also extensible. Note that whilst the schematic below may look complicated, its actually a very simple & cheap interlock based round a single 4013 dual d-type flip-flop and an output driver that is replicated for each positionin this example, 8 times. The buzzer is also optional and can be omitted, along with all its associated components. The few extra resistors & capacitors used for improving the noise immunity are very cheap but improve the reliability of the design greatly. i.e. it's a proper design rather than a hack! __ Designed by Nick de Smith

Flashing Birthday Heart - This circuit was made for my wife's birthday. It is capable of flashing five strings of LED's with different frequencies. It also has a connector for an 8 Ohm loudspeaker and two connectors for the small PCB's that are contained in musical greeting cards. In this way the circuit will play alternatingly two room filling tunes at regular time intervals. After a w __ Designed by Michel Van den Bergh On Electronics
