Alright guys I am going to be using an Arduino in my car to control a lot of my off-road lights. (7 of these: http://www.RigidIndustries.com/product-p/srseries10.htm)
So I need a relay that is 12V right? So I’m thinking this one here: http://www.sainsmart.com/16-channel-5v-relay-module-for-pic-arm-avr-dsp-arduino-msp430-ttl-logic.html
This will work right? I will be able to control up to 16 relays (that can control my 12V electronics) independently correct?
Thanks for the tips guys.
