I am making a launching mechanism on a miniature tank like structure.
For the launching, i am using to electromagnetic rods charged with opposite magnetic fields so that when they are momentarily activated, strong repulsion causes one of the magnets to move and launch the projectile.
The problem i am getting is that the electromagnets are being charged up via a 11.1 LiPo battery which will be powering the arduino as well( through an ESC). I need to figure out how to trigger the launching through a radio command sent onto the arduino.
Please help asap.

Thank You


You probably need to look at previous post concerning transmitters and receivers to see what others have used.
