G+_Talky Posted June 10, 2015 Share Posted June 10, 2015 Can anyone tell me if the arduino uno has monitor support or do I have to use a shield Link to comment Share on other sites More sharing options...
G+_610GARAGE Posted June 10, 2015 Share Posted June 10, 2015 Assuming you are referring to a computer moniter (or such), no. The arduino can run simple alphanumeric displays and kindof analog rca tvs, but the uno is just an avr microcontroller. Not a system on a chip. It dosent have enough processing power to drive a coplex display. Link to comment Share on other sites More sharing options...

G+_Talky Posted June 10, 2015 Author Share Posted June 10, 2015 610bob the raspberry pis gpio pins don't have it and I was wondering if the arduinous io pins have it Link to comment Share on other sites More sharing options...
G+_Gilbert Knarr Posted June 10, 2015 Share Posted June 10, 2015 Yes the Arduino has motor support. Link to comment Share on other sites More sharing options...
G+_610GARAGE Posted June 10, 2015 Share Posted June 10, 2015 Oh, ok. Then the answer is yes, no. :) The arduino can't run a motor directly. Motors draw too many amps. You need a power transistor, my favorite, mosfets, or some other gate that I can't remember. The arduino will tell the mosfets to turn on or off which controls the motor. If you want to control speed, you would just use a pwm signal going to the mosfet like a led. If you want forward and reverse, you will need to make circuit called an H bridge. I made many of these, and while the circuit is simple, I always end up burning at least on mosfet before I get it right. Simple answer would be no, but if any of that seems to be over your head, then just use a shield. If that sounds like something you want to tackle, then here is something that I found after a quick google that would be helpful. http://www.modularcircuits.com/blog/articles/h-bridge-secrets/h-bridges-the-basics/ Link to comment Share on other sites More sharing options...
G+_Gilbert Knarr Posted June 10, 2015 Share Posted June 10, 2015 Thank you 610bob for explaining it. I was typing something similar in after I accidentally hit send. Link to comment Share on other sites More sharing options...
