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 ...

This is tutorial number 1 from our series of Arduino tutorials and in this part I will talk about blinking an LED using the one already available on the Arduino Uno board or using an external LED to ...

This project demonstrates a simple LED flip-flop pattern using an Arduino Uno. The LEDs will toggle between different colors in a sequential pattern, creating a flip-flop effect. The circuit consists ...
