Controlling a servo motor wireless via an Android application
How simple is to control a servo motor wireless from an Android device? Very simple. The Instructables user Magesh Jayakumar shows us how to connect the servomotor to an Arduino board and program it in order to receive commands via Bluetooth connection from an Android device.
The Android application is built using the MIT app inventor and let you choose the direction of the servomotor using a progressive bar. The motor is connected to an Arduino microcontroller together with a HC-05 Bluetooth Module.
In this tutorial is explained step by step the procedure to build the application and to interface the servo motor with the Arduino board.
This is how the application works
