Introduction

Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio waves in GHz) from fixed and mobile devices. It was originally conceived as a wireless alternative to data cables.

We can use HC-05 Bluetooth Module to connect evive with phone Bluetooth

HC-05 is easy to use Bluetooth Module having Bluetooth V2.0+EDR (EDR: Enhanced Data Rate). It can be used as master and slave both modes programmed Serially and communicating Serially.

We can Use evive Bluetooth Application for the same Use.

Connections:

 

Here 9V battery is used as a power source. You can use Standard AC source instead.

Make sure that connections of bulb are made in NO and Common. 

Procedure:

  • Initialize Bluetooth to work with 9600 baud rate (for reference Bluetooth Setup)
  • Carefully connect all components
  • Start coding in ArduinoIDE

Coding Algorithm:

  • Initialize Serial Communication to work with 9600 baud rate
  • Select mode for Light as OUTPUT
  • Read data from Bluetooth
  • check Data
  • if data is L or l Turn On light
  • Else turn off light.
