Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

Animate multiple 24 VDC LED garlands with flashing and variable brightness (13 different parameters) with one Arduino Nano multi-tasking with FreeRTOS. After my previous project with one Arduino ...

The basis: 24V system of multi-coloured LED garlands for Christmas trees with 220V transformer and rectifier. The brightness of the garlands is fixed. Project: animate the LED lights with an Arduino ...

long current_time = millis(); //millis() - Returns the number of milliseconds since the Arduino board began running the current program. bool btn = digitalRead(BTN ...

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 ...

This library provides an interface to control an LED connected to a GPIO pin using PWM. The principle of operation as as follows: The PWM output is managed by a FreeRTOS task with a fairly low ...

Most projects are built on abstractions. After all, few of us can create our own wire, our own transistors, or our own integrated circuits. A few months ago, [Julian Ilett] found a problem using the ...

Perhaps one of the most common modules in an Arduino starter kit, the RGB LED lets you create all sorts of colors with just four pins from the Arduino. This tutorial demonstrates two ways to use this ...
