If you get the job From teaching science to electronics projects. Elementary education level. This project is right,as 10 LED roulette circuit using TC4011-LM4017. They uses the principles of digital ICs. Create an integrated LED flashing to the rhythm. And then stopped at one of the LED. Enjoy creating game. And knowledge From digital ICs.
Principles of GATE to produce rectangular frequency or pulse. And a counter circuit to see most familiar. This circuit so without creating problems for sure.
1.Random Number Generator circuit using IC-4017 and IC-4011
Firstly we see basic circuit before as Figure 1
This be Random Number Generator Circuit there is the character is 10 LED Flasher by use IC 4017 and IC 4011 integrated circuit. For the 4017 IC is a 16-pin CMOS decade counter. It takes clock pulses from the clock input, and makes one of the ten outputs come on in sequence each time a clock pulse arrives. Usability press S1 forLED Flasherrespectively. By pressure (Close) S1 make LED all stick dim (Dimly).
When liberate (open) S1 make LED stick bright at LED any one to one’s fate. Besides value expansion C1 be 4.7uF make LED flasher slow down. The detail is other invite friends see in the circuit leisurely
Random Number Generator circuit using IC-4017 and IC-4011
This circuit is worked as video below you can change C1-470pF,1uF,10uF or others. And IC-4017, you can TC4017,CD4017,MC14017,etc.
2. The 10 LED roulette circuit using IC-4017 and IC-4011
In Figure 2 is the 10 LED roulette that a game of my son.
How it works
When entering the power supply circuit, and switch S1 (Start), which is attached press release switch off. Then the current is flowing through R1, R2, and C2.
Makes the capacitor C2 caused up When the switch S1 allows the C2 to discharge through R3. The pressure this causes the clock input to the pin 8 of IC1a.
The IC1a which will work with production IC1b frequency to send it to the leg 14 (Clock) Of IC2.The IC2 is a driver by ICs LED 10 is illuminated by the moon to the incoming frequency.
The IC1d the IC1c and work together. It will serve up audio frequency generator, and then sent to the Piano Society (PZ1) loud beep came out with the LED light period.
