Some progress. I didn't build the H Bridge circuit. I went to Maplin asked about the bits needed and was met with glazed eyes - more glazed than mine! So I found this on ebay (see pic).
I have it wired and the best thing is it supports analog - so this micro RC car which had digital steering and drive now as analog running both.
My next challenge is to try run the lot on a 3.7v lipo attached the nodeMCU Vin - which "should" be for 5 volts. I've wired it and all the lights come on, but whether there's enough to run wifi and the H bridge plus motor I've no idea. Anyone?
If that works I'll refine the sketch and report back again.
Edit: Needless to say there is no way the body is going to go back on this car now.
