I have purchased a board kit called JectorRate. I have assembled it and tested it with no problems. The board requires 12v, 5v and ground to function. I am using it to test automotive fuel injectors and coils. While accessing 12v is not an issue, finding a 5v reference can be bothersome. I have investigated the 7805 as an addition to the board to regulate 12v to 5v. I have purchased a 7805 from Radio Shack and a heat sink (not sure if the heat sink is necessary, but would rather be safe than sorry).
My initial thought was to simply add this chip into the aprpriate points on the board. then after reading more about regulator circuits I see that caps are used (I would imagine to filter the voltage). My question is are these caps necessary and benificial or would my idea of simply adding the chip be sufficient?
I am providing the schematic for the board for reference. Thanks for any help that can be given. Please keep in mind that I am likely not as experienced nor educated as most here in electronics. I am a lowly auto tech trying to make my life a little easier at work
