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 ...

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 ...

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 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) ...

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 ...

Among all the Arduino boards, the Uno is most folks' go-to choice, and for good reason. It's the perfect platform to get started with Arduino, it's capable enough to handle a wide range of tasks, and ...

In adding an alternative cutter drive motor (‘spindle’) to an existing cnc machine, an electrically isolated pwm to analogue converter is needed. The machine uses a ‘grbl’ controller, which has an ...
