I got a relay that I want to use with my arduino, but I wanted to verify some things before I try so I don't end up with a dead pin. All of the specs on my relay can be found here: http://htyp.org/275-0240_Radio_Shack_5-volt_relay
It says it has a nominal current of 89.3mA. I am using an arduino UNO which says it can supply up to 50mA per 3.3V pin. How can I manage to make it work? Will I need to supply power from the 5V pin on the arduino somehow? Can I run my relay from 3.3V? How can I deal with the current supplied and the current draw from the coil?
I'm totally clueless about the subject. I've tried looking around for a while, but I can't seem to find any straightforward answers that I'm capable of understanding. Thanks for any help!
