I have receiving problems w.r.t board/shield.
It was working perfectly recently but later on when we put on the same codes as given by you and connected to USB; it didn't work.Instead after some time after multiple rewriting of the same gripper code; smoke came out of the Sheild;after which I immediately removed the USB
Now
- The sensors are working perfectly.
2.The lED 13 pin blinking program works.
3.The gripper works but after it reaches its max. orientation;it doesn't came back - On running the motor_ref code in which W= move forward; X=stop; A=turn right
The left motor runs continuosly backwards no matter what input is given in serial monitor.When we give an input which commands the left motor to stop;it slows down;but doesn't stop.
I am attaching two views of each arduino board and sheild as nothing seems to be burnt to me.
Please do help sir;as I am not even getting what is the problem;and way of troubleshooting.
