In this tutorial, we will explore how to use the Bluetooth Classic on ESP32 with Arduino IDE. For demonstration, we will establish bidirectional data communication between the ESP32 and an Android cell phone over Bluetooth Classic. Firstly, we will see a simple example to send data from ESP32 to an Android app. After that, we … Read more
In this tutorial, we will learn how to build an android app with a slider that will enable us to control the brightness of an LED connected with Arduino. The slider will be moved to set the slider value. In response, this slider value will set the duty cycle of the PWM signal generated by … Read more
In this user guide, we will learn to build an RGB LED Control Android App with MIT App Inventor and control it using Arduino. This Andriod app will allow us to change the color of an RGB LED by setting it from a color picker featured on the application screen. The transmission of RGB values … Read more
In this Arduino project, we will create a home automation system that will control home appliances via HC-05 Bluetooth and an Android application. HC-05 Bluetooth will be used to communicate with Arduino using an Android Application known as the S2 Terminal. There are also other apps but this is free and easy to use. To … Read more
