The code creates a smooth fading effect for multiple LEDs connected to specified pins on an Arduino. Each LED fades in to full brightness and then fades out, one after the other, creating a visually ...

• ledPins[]: An array that holds the pin numbers {8, 9, 10, 11, 12} where the LEDs are connected. • brightness: A variable that tracks the brightness level of the ...

I have spent at least an hour almost every day since the 80’s advancing my knowledge in electronics. Recently I brushed up my knowledge on LED fading secrets and attained something pleasant. Now, I’d ...

I came up with a different approach to let a LED fade in and out. When two separate squarewaves, with a slight frequency difference of about 0.5 Hz, are combined, the output squarewave pulsewith will ...

I'm sorry that I'm too late for the competition, but I want to show my proposal nevertheless. I used 2 constant current sources to load and discharge the capacitor C1. CC1 with an n- Channel J-Fet ...

Here is a 3D light show that will astound you with its combinations. Inexpensive and easy to make thanks to an Arduino controller, the design enables you to play with the existing effects and, most ...

Simple but effective all-analog fading LED circuit. This simple fading LED circuit is basically a relaxation oscillator based on a PUT (Programmable Unijunction Transistor) device, that is formed by ...

Arduino Micro has some extra leds that it is tricky to programme. Like almost all Arduinos, has a built-in led – the green one on the left in the photo. And it has a pair of yellow leds – called TX ...

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 ...
