Many Electronic circuit projects in simple ways of learning

LED light running arrows showing the position

This is a LED light running circuit with a number generated from IC CD4093, CD4520, and CD4094. This circuit can adjust the speed with resistors R1. When entering the power supply to the circuit IC1.

A NAND gate IC Oscillator generator circuit is connected to the input signal generator to pin 1 of IC2 and pin 3 of the IC3.

When receiving the signal from IC1 IC2 will serve up the signal from the logic into the binary.


Then sent to the pin 5 and pin 6 of IC1, IC1, which will process a NAND gate.

The IC3 is the signal from IC1 to processing and export of pin 4, 5, 6 and 7.Then entered into the base of the transistor pins Q1-Q4.

Any work on the transistor connected to the LED pin collector will glow out come.

For the format of the 17 LED Lights, arranged as a form of directional arrows.
