Hello - I have a simple application that I am looking at, trying to turn a series of small electromagnets on in sequence (not very fast). The intent is to pull an object along a track. Any suggestions on:
- Where I can buy small electromagnets?
- How do I interface them with the Arduino? Do I need to use a controller of some kind to provide the necessary current voltage? How many electromagnets can I control with one Arduino board? I would like to control 6 electromagnets.
- Are there any products out there that interface directly with the Arduino? One I have found is the Grove electromagnet.
Is there anything on the sparkfun site that is similar?
Thanks for any suggestions.
