Functional gameplay:
The lucky wheel is a tool that first predicts where the rotating disk will stop when it stops. It can also be used as number estimation games, electronic dice, lottery machines, etc. The electronic lucky turntable achieves the same function electronically. This kit configures 10 LEDs into a circle. When the power switch is turned on and the start button is pressed, each LED turns on in turn. At the beginning, the flow speed is very fast, and it looks like all the LEDs are flashing together. The flow speed will become slower and slower, and finally it will stop on a certain LED and no longer move. If the LED that lights up in the end is the same as the player's prediction, 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 multi harmonic oscillator. When the button S1 is pressed, Q1 is on, and the three pins of NE555 output pulses. The 10 output terminals of CD4017 take turns outputting high levels to drive 10 LEDs to emit light. After releasing the button, due to the presence of capacitor C2, Q1 will not immediately cut off. As the voltage at both ends of C2 decreases, the conduction program of Q1 gradually weakens, and the frequency of the output pulse of pin 3 slows down, resulting in slower LED movement frequency. Finally, when C2 discharge ends. Q1 cut-off, the 3 pin of NE555 no longer outputs pulses, and the LED stops moving. The 'lottery' process was completed in this way. R2 determines the speed of LED movement, and C2 determines the time to wait for the "lottery".
