I'm new here, hopefully this is in the right place and no double post.
My son and me a working on a remote controlled pirate-era sailing ship, and, among others, we are making remote controlled cannons. We have 16 of them.
For that, we use R/C glow plugs, 1.2-1.5 Volts, about 5 Watts. We would like to be able to fire broadsides (8 cannons) with a remote command, i.e., upon an analog Signal from the remote control Receiver (one signal per broadside), we want to fire the respective cannons in random order. I.e., the 8 respective cables leading to the cannons shall be put under power for a few seconds each.
I'm a Software dev, so writing up a program is the easy part - unfortunately I know almost nothing about electrics and electronics :-)
Is one of the arduino/genuino boards capable of doing this? Do we need relais or something? Ideally I would like to power everthing using the 6V DC battery already onboard our ship.
Help is much appreciated! :)
