Servo Driver
Archiver
Posts: 46,084
Hello all
I am in Mexico, and need help to build a servo driver, i have been
working with the basic stamp (is great) but for use we have to import it
from the states and there is none groups or support here.
Now I need to control a servo futaba but with a control (potentiometer)
or a stick or button with cable. Does someone have diagrams or specs to
build this ?
Thanks in advance and greeting from Mexico, please be free to conatct me
if coming here

I posted a potentiometer control circuit for a servo using a 555 timer
recently. I deleted the file. Maybe someone on this list still has it? If
not, I can reconstruct it.

Some notes:
* The cap on pin 5 is 0.01 to 0.1 uf.
* It didn't quite give full 90 degrees, but I didn't care. If you want full
90, here are the approximate equations to help you tweek it:
Thigh=0.7*Ra*C Ra is the sum of the pot and the 1K.
C=1uf
Tlow=0.7*Rb*C Rb is the 33K
It is easiest to mess with the resistors and keep C the same.
