What is PWM? PWM is a technique by using we can control the voltage or power. To understand it more simply, if you are applying 5 volt for driving a motor then motor will moving with some speed, now ...

This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...

It’s all started with a small game from the dark ages called “Mario”, right from the time of being a tiny little guy jumping on ducks to save my princess till being a masculine handsome Prince roaming ...

This Arduino sketch monitors the voltage output from a potentiometer connected to analog pin A0. It displays the voltage reading on the serial monitor and controls two LEDs based on the voltage level.

// the LED has to be connected to PWM digital pin // since LED connected to PWD pin accepts value between 0-255 and potentiometer provides value between 0-1023 we have to divide the value coming from ...
