This is a simple project that use a bluetooth channel in order to connect an Android application with an Arduino.
The aim of this sample is:
- Learn how Bluetooth serial channel works
- Learn how to configure a bluetooth device on Android
- Send a string from Arduino to Android (in this example the value of light sensor)
- Send a byte from Android to Arduino (in this example the LED ON-OFF status)
The Arduino schema is very simple
I’ve used an HC-06 bluetooth adapter, the cheapest (and slower) available on ebay. You can find the source code of the android application and Arduino Sketch file on my GITHUB repositories.
Now I’m ready to add bluetooth feature on my “HomeTemp” project.
