How To Make Android App To Connect Arduino via Bluetooth

In this project, we are going to make an Android App that will connect with Arduino Nano via the HC-05 Bluetooth module. This app will control the LED, motor, and read the temperature-humidity of the environment. We will use a free MIT App Inventor website for building app via blocks. We will give all the project files for this project. If you are ready let’s get started.

In this project, we will control the speed and direction of a DC motor using the PIC16F628A microcontroller. We will write the software in MPLAB IDE with the XC8 language that will sent PWM signal to L293D to control the motor. Finally, we will simulate it through the Proteus software.

You can get more information about the PWM signal from the link above. Now let’s examine the L293D motor driver.


Motor Speed Control With Arduino Nano

Motor speed control is very important in robots and where the motor used. In this project, we will control the speed of DC motors with Arduino Nano. In this way, you will learn how to drive the motor and adjust the speed in projects where you use DC motors.
