A couple of months back I stumbled upon Arduboy, a mini handheld game console which draws inspiration from the original Gameboy by Nintendo. As you can deduce from its name it is powered by Arduino. What this means is that it uses an Arduino compatible chip (the ATMega32u4) and can […]
High Voltage Arduino Pins
Maybe you have also looked at some Arduino circuits posted online and noticed an interesting way in how some circuits handle high input pin voltages. With high I mean anything above the typical Vcc + 0.5 rating given in the ATMega328p datasheet. Lets look at an example, in a previous […]
