Create a connected distance sensor with an ESP32 module

This short tutorial introduces the ESP32 module (a Lolin32 Lite) and connects an HC-SR04 Ultrasonic sensor. The entire prototype will be powered by a battery and sent its data to a webserver via Wifi. It is assumed you have installed the Arduino IDE and have some basic understanding of using electronics and wiring a breadboard. Although in … Continue reading Create a connected distance sensor with an ESP32 module

Using an Optical (IR) sensor with Arduino

This short tutorial introduces the Optical (infrared) distance sensor (Sharp GP2Y0A21YK0F). It is assumed you have installed the Arduino IDE and have some basic understanding of using electronics and wiring a breadboard. If you want to learn more or if anything is unclear, check out this extensive tutorial. Although in this example we use a display, you can … Continue reading Using an Optical (IR) sensor with Arduino

Build a distance-sensor with LittleBits

By utilizing the Arduino-bit and the Proto-bit, all kinds of electronic circuits and components can be connected to a Littlebits circuit. In this example, we connect an Ultrasonic sensor to the Arduino-bit with the Proto-bit. The distance measured by the Ultrasonic sensor will be displayed on the Number-bit. This example is based on the Bat … Continue reading Build a distance-sensor with LittleBits
