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 ...

All the info you need right here ✦ In this occasion I'll make a lighting system to be controlled remotely from my rc using ...

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… ...

So we can use a simple formula for routine calculations: “level = 255/5 x effective voltage” The experimental code for ATtiny85 is the same as the Arduino Sketch, as indicated. The only deviation is ...

Inside, an Arduino Nano is hooked up to a series of WS2812b LEDs. The LEDs are flashed in time with the heartbeat of the person holding the heart, thanks to a MAX30102 heartbeat sensor.
