Arduino as a wireless portable switch.

Hello,
I have a feeling this will be incredibly simple for someone who knows what they are talking about. I have seen a few projects on here for similar things, however all of them seem to be way too complicated for my needs.

I have this See Attachment ignore the wiring to the right hand side.
This is used to ignite rockets, its actually a firework sequencer , however I use it for a far simpler approach to step ignite multiple rockets without the need to re-approach the launch area (handy if there is a misfire, no need to approach the failed motor to set the next)
Currently used is a wired remote which transmits from a 9V battery to the input trigger terminals (input voltage is 3-70v)
What I would like to do is make this a wireless experience and I enjoy tinkering!

So I feel I would need a small wireless receiver, which I would like to use an Arduino as a base setup, which when triggered would send the voltage pulse to the device which would then start the sequence/initiate a step fire.

Sending a signal for the Arduino to output a voltage pulse to my sequencer. I don’t know whether I could do this with two Arduino devices, one as a trigger device and the other as a receiver, or am I better going down radio comms routes, but it needs to be secure, can’t have a stray radio signal setting one off. Needs to be from my trigger unit only.
It also needs to be a momentary signal, when my finger comes off the button it stops the Arduino sending the voltage.

Does this make sense?

Several other people have already done similar projects.

Try searching the forum for fireworks.

There are various forms of wireless communications available for the Arduino platform, and for security you can send a known sequence message. Yes a hacker could replicate it but you would not get a stray signal by accident.

Take a look at the NRF24L01+ for example, and its library.

Thanks, will look into the NRF24L01+ - I feel this task may be above my ability to be honest, head is being fried when hunting!
