After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

In this Arduino IR sensor module tutorial we are explaining how to connect IR sensor module with Arduino Uno and write the code to get the IR motion sensor working.

This library enables easy implementation of Ambient Light and Proximity Sensor AP3216 / CJMCU 3216 functionality in your application for Arduino (Arduino Uno, nano...), ESP32, ESP8266 (or similar ...

Arduino Code for ESP32 BLE Proximity Sensor For the demonstration, we will program our ESP32 controller to sense a known BLE beacon and we will light up the onboard LED once the known device is close ...

ExampleCode-AWiFi-with-Arduino This repository contains a collection of example codes demonstrating how to use WiFi with Arduino, focusing primarily on ESP8266 and ESP32 modules. These examples are ...

25-key ESP32 Touch Matrix makes good use of ESP32’s touch sensor interface Besides the addition of Bluetooth, there are many differences between ESP8266 and ESP32 and one of the lesser-known ...

This lets him alert the Arduino when an object approaches the sensor without the need for polling or extra code on the Arduino side of things.

The robot’s code resides on GitHub and the custom 3D-printed chassis is up on Thingiverse. If you like ESP32 projects you should be sure to check out the Monster Board and the Hamster Tracker we ...
