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 ...
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 ...
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 ...
Ejemplo básico de uso de PWM para control de LED con Arduino. Realizado para el dictado del Seminario de Sistemas Interactivos dictado en la Facultad de Artes - U.N.C. En la carpeta "img" se encuentra ...
long current_time = millis(); //millis() - Returns the number of milliseconds since the Arduino board began running the current program. bool btn = digitalRead(BTN ...
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 ...
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 ...
Community collaboration is a great thing. Take the Arduino PWM library for shift registers. Some folks at the Arduino forum pitched in and helped [Elco] trim off a bunch of clock cycles by using the ...
