Home Automation

I used an HC-05 Bluetooth module, a relay switch, a light bulb switch, and an Arduino Uno to create a wireless home automation light switch. The goal was to establish a wireless protocol for switching a light bulb on and off using a simple app on a smartphone. The relay switch controls the power to the light bulb, the HC-05 handles the Bluetooth, and the Uno reads the Bluetooth module to control the relay. The tools implemented can be extrapolated to other projects such as automated blins, controlled fans, motion sensors, smoke detectors, etc.

PARTS LIST:

  • Arduino Uno
  • Relay
  • HC-05 Bluetooth Module
  • LED Bulb And Holder
