sound-controlled-switch

In this project, we use two Arduino development boards, which are called master and slave. The master Arduino process the sound that received by the micorphone module. And the slave Arduino controls the serveo-motor to turn on (or turn off) the switch of some electronic device (e.g., a desk lamp)

Code Organization

• master_microphone/
  • microphone.ino: code for the master Arduino
• slave_motor/
  • servomotor.ino: code for the slave Arduino

Development Enviornment

We built this project by two Arduino Uno and serveral modules, namely Bluetooth (HC-05), microphone sound sensor (KY-037) and the servo-motor (SG90).
