Maybe you need a 2channel remote control key fob then.... They can be picked up really cheap on eBay....

Well if that's the only way, I better do some shopping then. eyeroll

Cheers Richard.

You can use something like this 5V Relay as an option... Plugs directly into one of the ezb's digital ports.... Using Set(D0, ON) and Set(D0, OFF) will drive the relay... This way you can turn your motor controller on or off using an ARC script or digital control...

That's cool. I went with the 2 ch remote in the end as I already have the set up in place. Thanks again Richard.

Just a comment about the hbridge at the start of this post. I used it to run 2 dc motors and run with arduino. When I send analogwrite value of 255 (motor full on) the supply volts of 13.7v drops to 10.5v on forward and 7.5v on reverse on the motor connections. This is also true if I just feed the PWM pin 5v. I found that I had to use a value of 254 as my full on PWM value and the the motor ran with virtually no voltage drop. Not sure why but seems to be a quirk of this hbridge.
