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.

Powered by an Arduino Uno, this laser tripwire alarm project ... servo motor to twist toward that light source. If the other photoresistor senses light coming from its respective direction ...

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 ...

This sensor allows us to interact with the external environment, through intensity of light. The photoresistor is based on light resistance, it will sense the light and will allow the microcontroller ...

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 ...

(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 ...
