Aside from the Uno and the ultrasonic sensor, you also need a PHPoC Shield to connect the board to the internet and a power supply to power up your Arduino. Throughout your workday, there may be ...

You can connect a 6 to 20V external power supply here, but the recommended voltage and current ratings are 7 to 12V and 1A only. The Arduino Nano and Uno are equipped with very similar processors ...

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 ...

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 Raspberry Pi is a credit card-sized computer capable of running full-fledged Linux distributions such as Raspberry Pi OS, ...
