Hi all,
I am working on small very basic project where I need a servo to open and close a small valve gate.
I am essentially building a miniature silo for a business expo display which will dispense M&M’s.
I plan to use an Arduino to open and close the gate using a servo. I will have to workout how far it opens and for how long with a try as I go to get the measure of M&M’s just right.
My actual question is:
What is the best and most powerful servo that I could use running it off the arduinos power? I don’t want to have to use any extra modules or power supplies if I can avoid it.
The servo will be triggered when a user inserts their business card into a slot (so we capture the customers details) and as a reward, the silo dishes out M&M’s from the loading spout underneath. For this I will use a simple beam sensor, when card falls through slot, breaks beam, activates servo open close function.
Thanks,
Chris
