Features

Breaking the Arduino Speed Limit

Admit it, we all like to do it — break the speed limit. Usually, it's just a little bit. Just how fast can you push the Arduino platform before it releases that magic smoke? Very fast, actually.


MakerPlot — The DIY Software Kit ... Part 6

See how to have MakerPlot send info to your micro of choice to control the firmware’s setpoint using a “slider”.
