How to make a switch to use with tx/rx?
I want to turn something on and off via my tx/rx on my quad which I am going to add later (I will show it when it is done!).
What is the best way to create such a on/off switch? Are there micro relays I can use?
It has to handle two AAA batteries in series, so about 3v@1A at full load.
I assume a relay as the rx is just a voltage which can open/close the relay to make the switch turn on/off.
I would have assumed loads of people have done something like this so any pointers appreciated.
