The main thing is the code, it uses Booleans. When we clap, the sound sensor sends a HIGH signal and it makes our relay status True or False.

Supplies

Electronics:

Arduino Uno

2-channel relay (any would work by the way)

Sound sensor

Lamp (any, but one with a switch will be easier to use)

USB Type-A to Type B cable (Arduino cable)

5V 1A adapter (a normal phone charger would work too)

Jumper wires

Tools:

Hot glue gun (to stick the components)

Screwdriver and pliers (to open the lamp and get access to the wiring and all...)

Step 1: Attaching the Relay to the Lamp

1. Open the lamp and take out the on/off switch

2. Remove the switch and connect the relay instead of the switch as shown in the circuit diagram

Step 2: Connections

4. Connect as per the diagram

Step 3: Upload the Code

Download the code and upload it!!

This is the link for the code.

Step 4: (Optional) Beautification

Make a closure for the electronics so that it doesn't look like a rat's nest.

Now it is ready to use!!!!!!

I'm not seeing any code in step 3.
