In this article I will add some simple Arduino LED projects starting with basic ones like how to turn on an LED, blinking, and more ... I love all about electronics, circuit diagrams and crazy ...

Microcontroller demo boards such as the Arduino UNO are ... communication circuit, and finally the lights. The video below shows a fully-functional Arduino happily running the blink program.

The Julia programming language is a horrible fit for a no-frills microcontroller like the ATMega328p that lies within the classic Arduino ... manages to blink an LED slowly.
