Here is the diagram of my Arduino infrared close proximity sensor. As you can see, the core part of my experimental setup is an Arduino UNO, but other compatible microcontrollers can also be employed.

The build relies on an Arduino Uno as the brains ... [Maker 101] gave the Arduino an infrared sensor which can pick up signals from a simple IR remote control. It can be driven backwards and ...

The code is an Arduino project for the Digispark Attiny85 to turn on a light source when the PIR sensor detects something ... Because an on-board “user” LED is wired to P1 of Digispark by default, you ...

(Source: Arduino) The UNO R4 WiFi version comes with an Espressif ESP32-S3 module for Wi-Fi and Bluetooth Low Energy connectivity. The bright 12×8 red LED matrix is ideal for creative projects using ...
