Function
Lucky wheel is a tool that first predicts exactly where the spinning disk will stop when it stops. It can also be used as a number estimation game, electronic dice, lottery machine and so on. Electronic Lucky Wheel is to reach the same function in an electronic way, this kit will be 10 LED configuration into a circle, when the power switch is turned on and press the start button, each LED order to take turns to light up, the beginning of the flow of speed is very fast, it seems that all the LEDs are like all flashing together, the flow of speed will be slower and slower, and finally stop at a certain LED no longer move. If the last light that LED and the player predicted the same, it means that the "jackpot".

Circuit principle
The circuit mainly consists of a pulse generator and a decimal counter circuit. Pulse generator by the NE555 and peripheral components constitute a multi-harmonic oscillator, when the key is pressed S1, Q1 conductive, NE555 3-pin output pulse, then the 10 outputs of the CD4017 take turns to output a high level to drive the 10 LEDs take turns to light. After releasing the key, due to the presence of capacitor C2, Q1 will not immediately cut off, with the drop in the voltage at the ends of C2, Q1's conduction program gradually weakened, the frequency of the 3-pin output pulses slows down, and the LED moving frequency also slows down. Finally, when the end of the C2 discharge. Q1 cut-off, NE555 3 feet no longer output pulses, LED stop moving. A "lottery" process is thus completed. R2 determines the speed of LED movement, C2 decides to wait for the "lottery" time.
