Step 10: Solder 5V relay

Step 10- Solder 5V relay and your kit is ready

Step 11: Connect the cathode point of clap switch module to the cathode point of relay module

Step 1- connect the cathode pin of clap switch kit to the anode pin of relay module

Step 12: Connect anode point of clap switch module to the anode point of relay module

Step 2- Connect the anode pin of clap switch kit to the anode pin of relay module

Step 13: Connect the JST connector of relay module to the + and – point on the clap switch module. The clap switch module gets power from the relay module.

Step 3- Connect the black(negative) wire of clap switch to -ve pin on the board and do the same for the red (positive) wire also 

Step 14: Connect a 6-9V battery to the kit and connect electrical lamp.

The connection between the kits is ready
