hi list,
i want to control two motors (pan&tilt). i looked into several options and this seems a good start: http://www.ladyada.net/make/mshield/ together with the arduino. i need a very smooth movement, so steppers from floppy drives seem a good option.
Steppers step, they are used to move the head from one track to the next but not in between, so if you want smoothness of motion, the gear motor that ejects the disk (either floppy or cd) is a better choice. You can control it using the arduino's pwm pins and an h-bridge like the mshield. Or the L298 chip is easy to set up and inexpensive, will drive two motors.
