I have been trying to get that code to run...the code in http://www.robot-electronics.co.uk/files/arduino_md25_i2c.ino When I run it, the only thing that happens is the LCD shows "MD25 Example V:" and that's all. The motors do not turn. I can see from the code that "MD25 Example V:" is the call to the LCD print on line 39. Why won't my motors run and why won't the program continue?
