The Arduino Motor shield is hooked up to an UNO board and links a motor and a 9V supply. Nothing special really – or at least, not now I know how easy it is. However it is a major step since code that controls the timing of ON/OFF is passed to the board which then controls the motor’s state.
Next things to do:
- resurrect the lego earth antenna – dust off and tidy up design
- motorise it
- draw up the new design which involves wax/substrate dripping from a reservoir held above the antenna device.
