1. Drag & Drop Arduino Uno and breadboard in the “designing area”. Then, Connect 5v of Arduino to the positive sign of breadboard and GND to the negative sign of breadboard as shown below.


2. Now, Drag & Drop three LEDs and resistors in the” designing area” and connect it in on breadboard as shown below.

3. Now, connect LEDs with Arduino Uno as shown below.

Red Led = Pin6

Yellow Led = Pin7

Green Led = Pin8
