Hi everyone, newbie here, I've compared a lot of the options out there and I've decided to go the arduino route. It seems like there is a lot of great hardware options and great support on these forums. I have a desire to learn not just the arduino modules but the components as well, please recommend any good books or resources if ya'll know of any.
Down to the project at hand, I'm looking to build a project that I can use to control automotive relays. I found this PDF on here: http://www.arduino.cc/playground/uploads/Learning/relays.pdf. Its great, but I'd like to take a step further and be able to control relays with a touchscreen, and perhaps even go a little further than just a on/off relay and have a dimming capability (for dimming 12v lights or LEDs).
A little help on what components to buy would be appreciated, so I can get most of what I need starting out, even if I'm not advanced enough to actually use it all right away. Thanks!
