This is many LED flasher circuit and with PCB layout using transistors astable multi vibrator as low frequency oscillator below more...[...]
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…
Many people would never suspect.IC is not Gates, frequency generator that? Will be deployed there? The rubber or how it works? This circuit will work to understand more easily.Because a…
A electronic friends was seeking a play circuits in your free time,a cheap and easy to made.This dice digital circuit would be a favorite of everyone, by using it to…
We used the two LED flasher with transistors only. Today we come to experiment the 3 LED flasher circuit by 3 transistors astable multivibrator,
The small Christmas LED flasher circuit is small and easy and cheaper than other circuit. It suitable for beginner. there are IC1- CD4093 as main,and 9 LED
