Thanks for that link Terry, it shows me a bit about the Motors i have. I got the 43362 and the NXT and also some of the older 2838 ones at home so quite a collection
I think i have the 43362 motor's sussed on that shield, but that was just trial and error as the documentation for what the "switches" on it does are a little sparse. (would i say be able to run a few 12V motor's through that board with an external 12v power supply"?)
With the NXT I read they have an angle sensor which i assume means it can be a lot more accurate movements, i assume that it will then have an input (power) and output (sensor value)?
The next thing is some of the sensors i have for the lego would be good to use as there is temperature, distance and LED which are always fun...
