Functional gameplay:

The lucky wheel is a tool that predicts where the rotating disc will stop when it stops. It can also be used as number games, electronic dice, lottery machines, etc. The electronic lucky wheel is to achieve the same function electronically. This kit will configure 10 leds into a circle. When you turn on the power switch and press the start button, each LED will light up in turn. Finally, it stopped on one LED and stopped moving. If the LED that finally lights up is the same as the player predicted, it means "winning".

Circuit principle:

The circuit mainly consists of a pulse generator and a decimal counter circuit. The pulse generator consists of NE555 and peripheral components to form a multivibrator, when the key S1 is pressed Q1 is switched on, the 3-pin output pulse of NE555, then the 10 output terminals of CD4017 take turns to output a high level to drive 10 leds in turn. After releasing the key, due to the existence of capacitor C2, Q1 will not immediately cut off, with the decrease of the voltage at both ends of C2, Q1's conduction program gradually weakened, the frequency of the 3-pin output pulse slowed down, and the LED movement frequency also slowed down. Finally, when C2 discharge ends. Q1 cutoff, NE555 pin 3 no longer output pulse, LED stop moving. A "lottery" process is thus completed. R2 determines the speed of LED movement, and C2 determines the time to wait for the "lottery".
