Dear fellow aviation enthusiasts.
I would like your guidance.

Objective: power 12v stickshakers once mobiflight detects a stall situation.
System: MEGA connected (via pin 2 and pos, gnd ) to a relay.(VCC = pos, gnd to gnd, pin 2 to IN+). The relay i am using is attached.
software: Mobiflight. i program pin 2 as led/ouput and use the inbuilt fsuipc offset for stall. the offset works no problem.
Problem. i cannot make the relay switch. I can only make the relay LED, light on and off (but only if i remove the GND pin?).

Thank you
Relay

Hi nicher,

welcome to MobiFlight!

It seems that you use a relay what needs 12V. The Mega directly can deliver only 5V because this it its operating voltage. You should use a 5V relay.
