Schematic of Arduino PWM LED Controller Circuit. Advertisement. ... With the help of the Power Mosfet, we can use the low voltage output from the Arduino ports to control high voltage/current loads ...

Here is an artistic Arduino project for the fun-minded. The circuit is an Arduino RGB LED controller running on a sweet ‘n’ simple code,but with a little hardware surprise outside the Arduino board.

Yet another, “flash a LED with an arduino” project. Report comment. Reply. Andy Goth says: July 20, 2011 at 8:10 am ... The ‘595 costs $0.083 per output, while the PIC is $0.073.

At the most an Arduino output pin can supply 40 milliamps. That’s enough to drive an LED or a pager’s vibrating motor, but anything substantial will require some help.

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… ...
