As you can see, the core part of my experimental setup is an Arduino UNO ... The series resistor R1 sets the operating current (and hence the brightness level) of IRED1. The infrared receiver IR1 is ...

After a youth spent playing with Amigas and getting into all sorts of trouble on the school computer network, I’ve always had a soft spot in my heart for hardware from the 80s and 90s.

While this can be used for basic HID implementations, [Nathalis] takes it a step further by using a series ... two Arduino Pro Micros are attached in parallel and receive signals from the Uno ...

The Arduino Uno, which is a popular microcontroller board ... This could be achieved by adding another set of LEDs that light up when the motorbike’s brakes are applied. This would provide ...
