I am not really an electronics specialist, but a software engineer (so excuses if I 'm asking stupid questions).
I am trying to use a microcontroller GPIO output rated at 1.8V. When this pin becomes high, I want to enable a 12V relay. I am using a N-channel MOSFET from freetronics
The specs for the MOSFET can be found here.
For some reason the 1.8V seem insufficient to drive the MOSFET although it is specified for 1.5V min. I've tried a standalone setup using a 1.5V AA battery and that doesn't work either. But if I apply 3.3V with the same setup, it works (just so you know my wiring is OK).
Unfortunately my microcontroller (Intel Edison) only has 1.8V GPIOs.
Am I missing something? How can I make this work? Should I use a different MOSFET? And if so, which one?
Your help is much appreciated.
