The Arduino Mega can blink LEDs using digital I/O pins and simple code. It supports multiple LEDs, allowing for complex patterns and PWM dimming to create varied lighting effects. - Projectslearner ...

This instruction is executed only one time. Next is the loop function that sets the pin 13 HIGH (+5V on pin 13), waits a second (1000 ms), then turns OFF the LED (0V on pin 13) and waits another ...

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 oscillato… ...

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, ...

The Giant LED Dance Floor, built for Furnal Equinox 2017 over the course of 11 months. Technical specs: – 64 panels, each with 4 cells, for a total of 256 cells (16×16) ...
