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 ...

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 ...

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 ...

The MultiPWM library implements a software PWM for AVR Arduinos with up to 16 bits resolution on any combination of digital output pins (e. g. Arduino Uno: up to 20 pins, Arduino Mega: up to 70 pins) ...

Knowing that I’m always happy to get something new and glowy, my wife brought home a cheap “floating pool light” that she found on sale for roughly $10. This is a large white floating ball that has ...

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 ...
