![]() ![]() The code for the project Bluetooth Controlled Servo Motor using Arduino is given below. To download this app, visit this link: “ Servo Motor Kontrol”. The layout of the app after connecting it to the Bluetooth Module is shown below.Īs you can see, the app provides two ways in which you can control the servo motor: using dedicated buttons or using the slider. I have used an App called “Servo Motor Kontrol” developed by “YSRGGS”. Since the job of Bluetooth Module is to transfer data received from Phone and transmit it to Arduino, I have used only its TX Pin.įor more information on HC-05 Bluetooth Module and how to interface it with Arduino, please refer “ Arduino HC-05 Bluetooth Module”. So, connect the TX of the Bluetooth Module to RX (Pin 2) of Arduino. ![]() I will be using a Software Serial option of Arduino and hence Pins 2 and 3 of Arduino are fixed as RX and TX. It is important that you connect the control pin to a PWM enabled pin of Arduino. Connect the Control Pin of the Servo Motor to Pin 11 of Arduino. Myservo.The design of the circuit for controlling a Servo Motor using Arduino and Bluetooth is very easy. Int pos = 0 // variable to store the servo position twelve servo objects can be created on most boards Servo myservo // create servo object to control a servo Written by BARRAGAN and modified by Scott Fitzgerald Make sure you have the ESP32 board selected, and then, go to File > Examples > ServoESP32 > Simple Servo.
