It seems like most of the controllers, these days, use wireless controllers.
I’m building something just a bit different - an electric walker (like old folks use). Essentially a very wide electric board, with a frame to hold onto, that goes really slowly (4mph tops).
I’m thinking of very simple controls - two motors, two slide switches (maybe just on/off buttons), tank-style steering (left motor only to go right, etc.).
Which leads to an obvious question: Any suggestions as to motor controllers that can take a wired input - bonus for a simple on/off contact closure - where the speed is simply programmed in?
