Introduction: How to Control Servo Motor From Android App
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
int bluetoothTx = 10;
int bluetoothRx = 11;
SoftwareSerial bluetooth(bluetoothTx, bluetoothRx);
//Setup usb serial connection to computer
//Setup Bluetooth serial connection to android
//Read from bluetooth and write to usb serial
if(bluetooth.available()> 0 )
int servopos = bluetooth.read();
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.
Step 4: Follow These Steps If the App Not Install on Your Android Device
go to setting in your android mobile select security and move to Device administration and give access to allow install app from unknown sources.
