I’m looking for a self-running driver with a DIR input.
What we want is to turn the power ON and motor starts moving and we only can control the speed and direction. Speed through the board and direction via a external signal. (0-5v DAC)
Can this be done or is there any already available PCB doing this?
I have some great robot kits by Makeblock that are fully programmable and can be made to behave the way you describe! Check out these:
You could always make your own with an Arduino and some motors! If you are new to programming in Arduino then I would recommend a kit that is geared toward learning the ropes like the Sparkfun Inventors Kit. This doesn’t include anything wireless though.
I hope that helps!
