Gravity: MOSFET Power Controller Introduction In most Arduino projects, relays are the first choice to drive some large current device. It requires a certain amount of current to drive the internal coil to pick-up contact. But for some MCU, like Intel Edison, Intel joule, lilypad, Raspberry Pi and other microcontroller with limited amount of current GPIO, it’s hard to drive one or more relays simultaneously. The MOSFET power ..
