Ever feel too lazy at night to get out of your warm, comfy bed to turn off your light? Do you always struggle to find the light switch in an extremely dark room? Forget to turn off your light after you leave your room?

We present to you… PhoneSwitch! Your phone will act as a remote control for your light. Simply press a button on your phone to switch on/off your light using bluetooth. PhoneSwitch: saving you time and energy, both essentials for the busy college student.

Technical Details

PhoneSwitch is composed of an Arduino, a power adapter, a Bluetooth sensor, and a cellphone. The Bluetooth sensor allows you to establish a wireless link between your Arduino and your phone. The power adaptor plugs into the wall and functions as a switch by allowing a certain amount of voltage (either 0 or all) to pass through. With the app, your phone is able to tell your Arduino to switch on and off the power adaptor.

Our Design

Challenges We Faced

We utilized an app that was provided with the Bluetooth chip; however, we initially had difficulty syncing the app with both the chip and the Arduino. We had to write code that would allow the Arduino to read signals from the Bluetooth and send a digital signal (ON/OFF) to the power adapter accordingly. The app also read each touch as two (press/release), so we had to keep that in mind when we wrote our code.
