This application was developed to make it easier for Android users to control their Arduino Uno via the Bluetooth serial port. 

How does it work?

You will need to install the app on your Android phone. It is an Android app that uses the Arduino Uno's Bluetooth serial port to send and receive data. It is free to download from the Google Play Store.

The app has three main sections. The first section is the app itself. The second section is the settings. The third section is the hardware. You will need to make sure that your phone and the Arduino Uno are paired. You can check this by going to the settings and then the Bluetooth.
