i have been trying to connect the air pump to my dobot M1 to begin using the suction cup, however every time i plug in the power and ground it short circuits the dobot and it restarts.
I have checked the wiring. It is done exactly as the Guide book specified. Ground to PGRND, red to Vcc, yellow and blue to out 17 & 18.
I have shortened the wires to make sure there is no air exposure, nothing is touching them. Any ideas what could be causing it, please let me know.
