It is a pretty common first project to use an Arduino (or similar) to blink an LED. Which, of course, brings taunts of: you could have used a 555! You can, of course, also use any sort of ...

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.

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 // ...

8×8 LED Matrix modules are now widely available, and fortunately they are easy to use with our favorite Arduino microcontroller ... Here we drive it in the serial manner in order to save interface ...
