When you read “Arduino wristwatch”, you fall into the trap of envisioning an Arduino UNO clumsily strapped to someone’s wrist. [Marijo Blažević’s] creation is much more poli… ...

The code is for directly controlling the LED matrix (I had made a 10X8 matrix) through Arduino Uno. Here, I have used multiplexing which makes the task a bit difficult to understand at first. But once ...

Touch Sensor LED Control Overview This project demonstrates a simple embedded system that uses a touch sensor to control an LED. The code is written in Embedded C for an Arduino Uno and compiled using ...

But there are really just the two speeds with the current programming. Inside the cool laser-cut box is an Arduino Uno and a 9V battery, plus a current-limiting resistor and the all-important buzzer.

Arduino says these additions allow for more advanced projects. Besides Wi-Fi and Bluetooth, the UNO R4 Wi-Fi has a built-in LED matrix with 96 dots arranged 12x8.

Massimo Banzi, co-founder and chairman of Arduino, announced the UNO R4 during Arduino Day 2023. He believes the UNO R4 is a new chapter in the UNO story and the perfect way to move forward, ...
