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.

Original Circuit Diagram: Arduino UNO R3 Now, have a look at our favorite Arduino UNO to find out the AVR chip inside. It is ATMega328P-PU, a low-power version of the traditional ATMega328-PU. The P ...

The official Arduino team has this week revealed ... voltage and form factor are unchanged from UNO R3, ensuring maximum hardware and electrical compatibility with existing shields and projects.

Most of us are familiar with the Arduino Uno, a starting place for electronics projects since 2010. But what if the Arduino Uno was released in 1980? You’d probably get something like ...
