Yesterday i tried to stack some shield (motor shield) on a shield (servo motor shield) already stack on my arduino Uno.
But i realized, that i have some problem when i try to use both of them. Seems like some energy lost or the stepper motor connected to my servo motor shield move weird slowly.
I already check online, and i found some explanations about stack many shields. About be sure thes shields don't use the same pins or SS. As a beginner, help would be very helpful. Thank you
Here is the two shield i use.
- Smart Servo Shield for dynamixel Arduino Motor Shield Rev3 — Arduino Official Store
- Smart Arduino Digital Servo Shield for Dynamixel AX Smart Arduino Digital Servo Shield for Dynamixel AX - DFRobot
wiki for dynamixel servo shield : Digital_Servo_Shield_for_Arduino_SKU_DRI0027-DFRobot
On these links , can found all the spec with the pin use. I think have some pin shared by both of them... But not sure
Some people have a solution please ? Many thanks in advance
