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
In this ESP32 guide, we will show you how to build a pulse oximeter web server using MAX30100 pulse oximeter and heart rate sensor. This sensor is used to measure heartbeat/pulse rate in BPM and blood oxygen concentration (SpO2) in percentage. The web server will display the current beat per minute (BPM) and blood oxygen … Read more
