Faulty servo? PLEASE HELP
Hi! i did some of the tests in the book for the servos. one works GREAT, it was already centered and it works perfectly. the other one however, ony hums. on all of the tests it just hums. when i adjust the potentiometer, the hum will change frequencies. it does nothing but hum. im wondering if i have a faulty servo? (i have the board of education Rev c, battery powered via 4 double a's)
please help! or direct me where to request a replacement. would this be provided free?

What you describe happens to me when the servo is plugged in backwards. Are you sure that you've got the white, power and ground clip properly plugged into the servo header port on the Board of Education? Also, try swapping servos - put the "non working" servo in the "working" port and see what happens.

thanks for the quick reply and help!
edit: and by the way, the servos will respond to a power on and move briefly. thought it might help the troubleshoot.

This problem is typical of a low or missing power supply. You can only program the BASIC Stamp if it is powered. Make sure you've got the 3-pos switch in 1 or 2, then try to program. Let me know if this was the problem. Also, are you using the USB BOE or Serial?

EDIT: the power light is coming on, what i meant was that theres a bad connection from the serial i think. sorry for confustion.
Did you check the batteries yet, or insert known good batteries? If not, please do so.
