A new Arduino Scratch programming extension has been released this week for the Arduino platform as an experimental option, that communicates with the Firmata firmware on an Arduino boards. A new ...

This water sculpture can stop drops of water in mid-air. This is accomplished by flashing LEDs to illuminate the droplets at just the right time. But it’s not limited to blinky lights alone. The top ...

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 find that I learn an immense amount of information by using examples — seeing how other people do things and understanding the “why” of their decision-making process. With this in mind, and by ...

The 8x13 blue LED matrix is also an example of using PWM to implement gray-level images. The LEDs are connected in a row/column layout in the form of a tree – the first row has one LED pair, the ...

We never did crack open our Etch-a-Sketch, but we did scrape out a window large enough to really check out the mechanism inside. [MrLangford] is bringing the Etch-a-Sketch into the 21st century while ...
