About: I make hobbyist stuffs and play with electronics follow me to know more

If you are looking to make Android app to control a servo motor, this is a perfect instructable for you, here you can follow a step by step procedure video to know how to make an android app using MIT app inventor and to control a servo motor.

Step 1: Circuit Diagram

I've used 3 components here

1. Arduino uno

2. HC-05 Bluetooth Module

3. Servo motor

Connect the components according to the circuit diagram.

Step 2: Program Your Arduino



Servo myservo;

int bluetoothTx = 10;

int bluetoothRx = 11;

SoftwareSerial bluetooth(bluetoothTx, bluetoothRx);

void setup()



//Setup usb serial connection to computer


//Setup Bluetooth serial connection to android



void loop()


//Read from bluetooth and write to usb serial

if(bluetooth.available()> 0 )


int servopos =;





Step 3: Create Android App

Follow the video below and complete the program for creating your app.

After completing the Program in MIT app inventor, go to Build and select App( save .apk to my computer)

Transfer the file to your android mobile phone or tablet.
