Microcontroller Tutorial part 1: What is a Microcontroller?

This is my first of five posts in this microcontroller tutorial series. Throughout this tutorial, I will be building a microcontroller circuit while documenting the process. By following what I do, you can make your own at home. My goal is to make a circuit that is as simple as possible, and which...

How An electronic oscillator works ???????

An electronic oscillator is an electronic circuit that produces a periodic, oscillating electronic signal, often a sine wave or a square wave. Oscillators convert direct current (DC) from a power supply to an alternating current signal. Energy needs to move back and forth from one form to another...

simple water level indicator.

the the level of any conductive non corrosive liquids can be measured using this circuit. The circuit is based on 5 transistor switches. Each transistor is switched on to drive the corresponding LED , when its base is supplied with current through the water through the electrode probes. One electrode...

Easy way to Test Transistor is working or Not .

The purpose of the transistor tester circuit is to test the NPN or PNP transistor whether they are working fine or not.So,i decided to provide you the simplest circuit that can be built on breadboard.I think this is the most simplest circuit ever to test the transistor and it works fine.You just need...
