Lucky Rotary Suite Electronic Turntable CD4017 NE555 DIY Parts And Components

Functional gameplay:

A lucky turntable is a tool that predicts precisely where the disc will stop when it is stopped. It can also be used as an estimate number game, electronic dice, lottery machine, etc. The lucky electronic turntable achieves the same function electronically. This kit configures 10 LEDs into a circle.

Each LED rotates when the button is pressed; the flow speed is slower and slower, then stops at a certain one. The LED no longer moves. If the LED illuminated later is the same as predicted by the player, it means “winning”.

Circuit principle:

The circuit mainly comprises a pulse generator and a decimal counter circuit. The pulse generator consists of a multi-vibrator composed of NE555 and peripheral components. When the button S1 is pressed, Q1 is turned on, and when the NE555’s three-pin outputs a pulse, the ten outputs of the CD4017 alternately output a high level to drive 10 LEDs to emit light.

After releasing the button, Q1 will not be cut off immediately due to capacitor C1.

As Q1 gradually weakens, the frequency of the output pulse of 3 pins becomes slower, and the frequency of LED movement also follows. As the voltage across C1 decreases, the conducSlow down. Slow down. Finally, when the C1 discharge is o1 is cut off, the NE555’s 3 feet no longer pulses, and the LED stops moving. A “winning” process was completed, R2 date you completed a “winning” process, and C1 decided the time to wait for the “winning”.
