Help! Servo is only turning clockwise
January 23, 2009
My servo is only turning clockwise the same length everytime no matter what number I have in my code.
servo 0, 150 or whatever number. It goes until it hits the end.
I have 3 wires black red and white. The black is on the pin I soldered on the Picaxe 28x1.
I have a standard servo that I bought here: http://www.hvwtech.com/products_view.asp?ProductID=878
Everything else is working. My SRF05 led is blinking when I imput the code. And my motors are working with the code.
I do have 2 other pins I have added on 1 and 2 for 3 servos but am only using 0 to start. I have checked all my solders and there are no bridges and they look clean.
Now I understand that Version 4 has LED Display serial interface issues but not servo issues that I can see. I do have version 4 firmware and am waiting on my new chip. Just trying to do the start here robot to see if I can get it to work.
I have a 1/2 330 Ohm resistor on 0 where the darlington chip was. Everytime I upload code to test the servo it does move a little but only clockwise.
Thanks for your help. :)
