In this tutorial, we will learn how to build an android app that will control the outputs of ESP32 over WiFi and internet using an Android App. We will control the output GPIO pins of the ESP32 module by toggling the two LEDs connected with the GPIO pins of the module. This android app will … 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 user guide, we will learn to build an Android App using MIT App Inventor and display temperature readings acquired from DS18B20 sensor with Arduino. The transmission of sensor data will be through the HC-05 Bluetooth module. Our Android application will display sensor readings on our smartphones. The sensor readings could be accessed anywhere … Read more
