I am controlling a DC motor via a Pololu VNH2SP30 driver. The microcontroller I am using is the Arduino Uno. Power for the Arduino is coming from the USB port, so its 5V and the VNH2SP30 also gets its 5V from there.
All works well, no problems. Now I want to try using a Wemo D1 mini so I can make it an IOT device. Am I correct that this will only work if I put a Logic level converter in between as the Wemo runs on 3.3V logic?
