Let us look at the currently available commonly used breadboards here in India. You can see in the above image four breadboards of different sizes. The bigger ones are of Full size, the one on the left is Half size, the one at the top left corner is the Mini size.
Today we will go through the Fade program that is found in the Arduino's IDE at File - Examples - Basics. The Components we will need for this experiment are Arduino Uno board, a breadboard, a led, a 220 ohms resistor, and two connecting wires. I have used a yellow and a black wire.
