ok her goes I have a rovio robot and am trying to make it a 4x4 for out doors,i now have +5volts on input that come from rovio wheels going into arduino inputs and the out put pins going to rc 4x4. Now my problem is i have +5 to +6 volts at the pin inputs but am only getting +2.45volts out for the fwheelpin and rwheelpin put,lturn and rturn i get +5volts on all out put pins like i should and does run the wheels on rc 4x4. is there something wrong wih my program? i tried 2 different ones and same problem.
