Re: Choosing RC Servo Controller

Thankyou everyone for your help on this issue. Perhaps a few more
details about my situation would help! I've got some specialist
custom electronics already built that's used for accurate stepper
motor control - we use this already in applications such as moving
syringes (for use in scientific laboratory pumps). I'd like to use
these electronics to combine the syringe pump with a valve that
switches between two positions. The valve is moved with an RC servo
motor. The motor drive electronics includes some 0-5V digital IO
lines, but they're not suitable for creating the PPM signal required
for the servo motor.

In the light of the responses here I think the easiest thing for me to
do is to build my own controller using a 555 chip which I can control
via the IO lines. I know this should be straight forward, but I
didn't know whether there was a controller board already out there
that does what I want.

Thanks again for the help,
Rob
