Step 4 Observe the result.

Output

When we connect all the parts together, slide the switch to ON, the RGB
LED light will turn on and shine in different colors. The power from the

battery travels through the jumper wires and resistor, reaching the RGB

LED. If everything is connected correctly, the LED will light up in the
chosen color and stay on. If something isn’t connected properly, the light
won’t turn on, and we will need to check the connections.

Application

This RGB LED circuit can be used
in decorations for parties and

celebrations. By changing the colors of
the LED, it can create a fun and festive

atmosphere, making the space look
vibrant and exciting. Additionally, it

can be used in night lights that change
colors to create a calming effect in a

room.
