multiple servos

How do i control and hook up multiple servos to the bs2. I bought an 8 servo
controller from pololu and it turns on but does not work and the red indicates a
fatal error that prevents further operation and another yellow led that
indicates a neutral or out of range position. Either way i have to control 2
servos and im angry that i have wasted money on a servo controller that does not
work and im open to any suggestions.

work call up the company and get your money back. I've had the best luck
with Scott Edward's Mini SCC II www.seetron.com. The Mini SCC II can control
up to 8 servos or you can daisy chain 2 or more controllers together to
control a huge amount of servos. Since you only need to control 2 servos
you might be able to get off cheaply by having the stamp do all the work.
Wiring the servos to the stamp is very easy power + & - to VIN & VDD.
Control line to the stamp's I/O pin.
Here's a simple demo program (for the Boe-Bot technically but it's the same
way for controlling non-continues rotation servos)...
right_servo con 0
left_servo con 15
i var byte
for i = 1 to 100
pulsout right_servo,850
pulsout left_servo,650
pause 20
next
end
The key is when you're repositioning the servos is to make sure the stamp
runs through the pulsing code enough times to make sure the servo has moved
to the desire position. Of course this is the advantage of an external
controller. So it comes down to would you rather do more work getting it to
run correctly in software and save money or would you rather invest in the
Mini SCC II saving a fair amount of work on software but costing you more
money?
