eBay NE555 DIY Kit Electronic Production 10 LED Lucky Rotary Suite Components New Features 1. The circuit is mainly composed of a pulse generator and a decimal counter circuit, which is simple to operate; 2. The pulse generator consists of NE555 and peripheral components to form a polyharmonic oscillator with stable performance; 3. This kit configures 10 LEDs into a circle, which starts to work when the power switch is turned on and the start button is pressed, which is simple to use; 4. The use of full process processing, large pads, thicker wires, component layout is beautiful; 5. The circuit is especially suitable for beginners, fun, effective and low production difficulty. It is the material for assembly practical work, skill training and so on. Specification Color: black Supply voltage: 6V Battery type: CR2032 PCB board size: diameter 68.8MM 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.
