Hi everyone,
Very new to electronics and just need some once off help, I think. I am a software developer but I require some indication lights for my Windows based software. I have picked up a thing or two and programmed a pic12f683 to receive commands serially and turn pins high based on the command. Everything is working, but I obviously cannot add a real load to one of these pins since they are only 25mA and 5v.
I have 2 Strobe Beacons that I want to connect to each pin, they are 12v DC and 800mA each so I need an NPN Transistor I just have no idea which one! I dont think a relay is required, since it is only lets say 1Amp (800mA so 1Amp to be safe?) I know how to wire up the transistor and such, I just don't know which transistor and what resistor to use with it.
Can anyone be so kind as to advice me on a part number suitable for my needs?
Thanks in advance,
Ross Steytler.
