Systematic Testing and Debugging
• Have the devices been properly interfaced?
• Use Mode 0 (Jumper J16-Pin3 to ground)– Do you have control of the wheels?– Forward, Reverse, L_Turn, R_Turn, Repeat
• Use Mode 1 (Jumper J16-Pin3 to 3.3V)– Are you receiving correct information from the
sensor board?– 101 = Both, 011 = R_Motor, 110 = L_Motor
