Arduino

Connect the wires:

In this step, we connect the LEDs with the Arduino with three different pins on the anode (+) and we connect the cathode (-) with the ground throw resistors to control the current.

The connection


Write the code:

In this step, we open the Arduino app on the computer and we connect the Arduino, then we start writing the code.

First: 

We need to define pins with its modes in the setup function.

Second: 

For every pin, we give the pin a HIGH signal, then we put a delay for some seconds, then we give it LOW signal to turn it back off.

The code


Upload the code:

In this step we press the upload button on the Arduino app, then we watch the circuit work.
