Here are LED light sequencer circuit that using IC-4017 and IC-555.
If you want to build a 10 LED Chaser circuit we suggest this circuit first. It uses popular IC is a simple and affordable IC-4017_decade counter and IC 555 [...]
This is simplest automatic solar led light circuit that my son try to make it for basic small solar charger. to use 2 x AA NI-MH battery total 2.4V
The 1.5v led flashlight circuit which also use single AA 1.5V battery. But few parts. Such as we use one transistor only. And all other parts of 5 pcs only [...]
This is first mini emergency light of my son. It is very small, use LED display when power outage,use transistor instead relay use AA battery charger.
These circuits are simple One LED flashers that use transistors as the main (first circuit), the transistor UJT (second circuit) and IC Op amps (the Third), Read more below. Using…
I am going to show you, LED Decorative light circuit. Do you like a LED blink or running light? I like a circuit like this. Although you will do not…
