Undecided Question: wireless receiver/romote on a battery?
Asked: Undecided Question: wireless receiver/romote on a battery?
I have a car alarm horn that I want to make wireless. So that I can turn in on and off from about 20 feet. i need a little help setting it up. any ideas?
this won't be simple
most of the switches/remotes that are commonly available run on AC power
your best bet would probably take a cheap RC toy, and strip it down, and then either get a switch or just use the motor to complete the circuit when you press the button/trigger on the remote.
