Nano Current Meter using ATtiny84
David Johnson-Davies published another great tiny project. He writes: This project describes a simple low-current meter I devised to check the sleep current of different microcontroller circuits, such as ones based on AVR microcontrollers. It's capable of measuring currents of between...
