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.

As a perfect example, these LED “blinking eyes” were created by [Will Moser]. Using nothing more exotic than some bare LEDs, an Arduino, and a cardboard box, these little gadgets can quickly ...

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. Every step will have the code, the schematic, photos of the project ...

End Update Here is ‘blink’ modified to work TXLED and RXLED as well as LED-BUILTIN int RXLED = 17; // The RX LED has a defined Arduino pin int TXLED = 30; // The TX LED has a defined Arduino pin // ...
