At Engblaze, we’re somewhat obsessed with squeezing every possible bit of performance out of our circuits. Ok, really obsessed. Like beyond Facebook-stalking and into restraining-order-territory obsessed. To that end, we consider it our duty to bring news of other intrepid performance squeezing pioneers in the DIY electronics world.
Have a power hungry Arduino and looking for a dead simple solution? Fear not, hardware hacker. The community has come to your aid. There are several libraries available that abstract all of the gritty AVR commands needed to make your Arduino drowsy.
