Hey guys!
I have an IR reader that needs between 2.7 and 5.5V to function, so I'm just gonna plug it into the 5V port on my arduino.
However, it also has a max supply current of 0.56mA.
Do I need a resistor? Because R = V/I; R = 0/.00056 => R = 0 (?)
Thanks for the help!

No, you don't need a resistor. You need to supply AT LEAST 0.56 mA at 2.7-5.5V but any 'extra' available won't be used and won't be a problem. You can hook it up to a 30 Amp 5V supply and it would work just fine.
Thank you!
Would you care to post a link to your IR reader
