Topic: Adafruit Feather Fona for GSM relais, stuck rn. (Read 57 times) previous topic - next topic


Hello guys & girls,

For my first project i'm trying to make a GSM relais that can switch off/on my computers adapter cable. I'm looking at the Adafruit Feather Fona 3.3v to reveive a textmessage. On recieving the textmessage i want it to cut the power and switch it back on.

Does anyone have any experience with this? Right now i'm stuck on what I should use to switch the power off/on since most relays need 5V to be triggered.

Really hoping someone can point me in the right direction.
