I’m working on a project that involves using all 4 ports to run 8 DC motors. I have been successful in using Ports 1 - 3 to run 6 motors, however I cannot get Port 4 to work. Here is what I have tested and tried so far:
1 - tested different combinations of motors I know are working on other ports
2 - swapped Makeblock Megapi Encoder/DC Motor Driver from other ports
3 - tested using “MeMegaPiProDCMotorTest1.ino” code included with Makeblock Arduino libraries, all Ports except 4 work
I have even purchased another Megapi board because I though maybe it was an issue with mine, but I have the same problem.
I feel like I’m missing something obvious but I’m not sure what that is. Could it be a power issue? I am running the board off the 6X AA battery power supply that is included with the Ultimate kit.
Any help or suggestions would be greatly appreciated.
