I have my Arduino based alarm sytem and found a 12v 500mA alarm-flashlight which I would like to use.
Now I have 2 problems here: 1) where do I get the 12 V 500mA from? Battery with step-up? Need a 12 v charger? 2) how do I control this flashlight? Relay?
Can anybodysteer me into a direction? Idealy with a ready-to-buy solution from some vendor, because I am more the programmer guy and not the solder-iron-savy guy..
Any hints are appreciated.
