Hello,

I am totally new to the Arduino,  so forgive me if I sound stupid!! this is a massive learning curve that I am relishing ? Anyway to my issue, I have used Bills tutorial " wireless joystick for Arduino robot car" and modified it to run my Elegoo car, I also had to rewire the l298n module and tweak the code, but to my amazement and some luck and lots of my time! it works absolutely  fantastic...it really does ? ? ?

The question is, I have added some Laser headlights and some led rear lights and would like to be able to turn them on and off remotely, but I can not find a way to do this with the Radiohead library. I want to learn how to do this rather than be shown so I am looking for some guidance, a starter, a little help! a web link, i have searched high and low but to no avail!! Maybe I am missing something? Please help and thanks in advance..Cheers. Also not sure if and how to post the sketch I have altered .. sorry ?
