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.

This build is about using the temperature sensor in your clock. The ATMega328p, the chip at the heart of all your Arduino Uno clones, has within it a watchdog timer that clicks over at a rate of ...

the Arduino Nano and Uno come with several similarities, and conveniently, they can be used almost the same way. You can program them with the same software, and many sensors are compatible with ...

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 WiFi version comes with an Espressif S3 WiFi module, that will help to expand creative opportunities for makers, educators, and hobbyists according to Arduino. The UNO R4 maintains the same form ...

(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 ...
