Ping mounted on a servo

raoramana

How do I test the rotation of the servo and the operation of the Ping sensor. I tried connecting the two to pins 16 and 17 with the 5V jumper but there is no response from either the servo or the Ping sensor. I tried substituting the pin no in the test code ans still no response. What is wrong here? Thanks

I'm in the process of building a roaming bot using the Propeller Activity Board and have learned very quickly that my Futaba S3004 servo will cause the activity board to reset when using the on board +5. Instead I included a 5 Volt LDO regulator to provide the +5 for both Ping and servo and the board no longer resets. My power source for the electronics is a 7.4 volt LiPo. I don't connect the servo directly to the battery since when fully charged it puts out over 8 volts which will stress the servo.
Even if I had a smaller servo I would still use a separate 5 volt supply to keep the activity board power clean and not stress the on board 5 volt regulator.
