The Ping Radar and object detector are on our BOB Robot and it starts working Fine with my Digital Ports - Then the Ping just drops out. The Object dedector sticks at the max distance and there are no red blips coming up on the Radar. I'm also running a servo for the head rotation tied in with the ping. Could this be due to low voltage to the EZ-B board ?
I checked tha battery pack and I'm getting 6.4 volts.
