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 ...

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 ...

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 ...

Sure, the physical build itself looks great, but it’s what [Michael] did with the firmware that impresses us the most. He’s using an Arduino Mega to drive the 7x7x7 cube and manages to squeeze out ...

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 ...

Anyone can hang a poster from the wall, but if you're willing to put a little DIY into your home decorations, this Arduino-powered LED wall-art looks amazing, and reacts to music playing in the room ...

This 8x8x8 LED cube with 512 LEDs takes the old 3x3x3 light cube made up of 27 LEDs to the nth degree. This, certainly more time consuming project, actually involves a simpler design. By using a ...

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 ...

Austriamicrosystems has introduced the AS1121, a 30V, 40mA, 16-channel LED driver with 12-bit PWM (pulse width modulation), dot correction and diagnostics. It is a 16-channel, constant current-sink ...
