By controlling analog circuits digitally, system costs and power consumption can be drastically reduced. Arduino already include on-chip PWM controllers, making this effectuation easy. In short, PWM ...

In this article I will add some simple Arduino LED projects starting with basic ones like how to turn on an LED, blinking, and more. Every step will have the code, the schematic, photos of the project ...

LED Circuit Driver (60¢): Circuit drivers are used in place of complicated electronics code.

The Casio SK-1 keyboard is fairly well-known in the “circuit bending” scene, where its simple internals lend themselves to modifications and tweaks to adjust the device’s output i… ...

The Arduino can just increment the counter up to the appropriate LED. The Arduino then controls the state of the LED using the active high enable line from the column multiplexer chip.

And honestly, a cheaper hobby to get into. With small Arduino boards becoming more popular, Olympia Circuits is jumping into the mix with the Arno Shield.

The official Arduino IDE is a dour piece of software designed for uploading code to the ubiquitous and super-cool micro controller. It is a standalone, non-networked app that isn't very pretty to ...

The Code Kit is an Arduino system in a box. It comes with a small rechargeable battery that can power an Arduino-based CodeBit with three inputs and three outputs.
