I am facing a problem. I bought a grove sound sensor that has 4 pins ( Sig- Nc-Vcc-Gnd) and i want to execute the program that turns on a lamp when clapping and turns it back off when clapping again
I don't know how to connect the sound sensor with the lamp. please help me
Start simple. First learn to turn on and off an LED with the Arduino.
Then learn how to connect and use your sound sensor. Grove provides examples for Arduino.
After you have figured out how to turn on and off an LED when you clap your hands, it is time to start thinking about the lamp.
