IR board help

[Ziaholic]

we cut up some PWM cables, for the 3-wire male and female ends. The IR's command outputs from the ribbon cable need to get spliced into 4 separate PWM cables ... but only the signal pin ... you can leave the + and - wires unconnected.

on the provided ribbon cable, pins 1 & 2 are (+) and pins 3 & 4 are (-). the next 4 wires are the outputs for CMD 0/1/2/3.

we just wired up those 4 single signal wire, to the 4 inputs on the Dig I/O on the RC. As long as the IR sensor board is getting the same power source as the RC, you are good-to-go, as they have a common return.

Your standalone 9v battery solution won't work reliably unless you tie the (-) side of the 9v battery to the (-) side of your bot-power. Without a common return, you risk zapping either the IR board or the Digital inputs of the RC.


For the connections, during our testing we simply used M and F spade lugs, crimped onto the ribbon cable ... not sure if we'll keep it for the final build.
