Hi.
I made a sketch for Arduino UNO to control 20 servos. Or it can control 18 servos width serial commands.
A video demonstrating the sketch:
Serial command example:
#0 P1000 #1 P2000 T2000 - Move Servo 0 and servo at the samt time from current position to 1000us and 2000us in 2 seconds.
The code was too long to post here so I attached it as a file
More explained at my blog : Arduino UNO Controlling 20 Servos With 15 bit Precision And Low Jitter | Lamja.com
I hope this can be useful.
Regards
Arvid
