I have a little free time today so I'm going to try and build another little homebrew Arduino. I finally have all the components recommended in this thread: http://arduino.cc/forum/index.php/topic,114860.msg865784.html#msg865784 plus some header pins, screw lugs, cable, etc.
I was going to include a couple of voltage regulators to separate the processor from the motors and include 5 or 6 male pin "slots" for hobby servos with separate power and signal from the processor. Plus maybe some leds to indicate servo function. For power to the board I was going to use some little screw lugs so it will be easy to switch from different battery packs to bench power etc.
I was also going to include a couple of 2X3 plugs for plugging other stuff into the board in the future. Maybe have them break out 5V and GND along with some pins.
Any advise/ideas would be great! Especially on laying out components on the prtoboard. I'm going to start with paper instead of the soldering iron this time :P
I was also wondering about what pinout I should use for this cable:
I've been programming my other little board with individual jumpers but I decided to make a cable so I wouldn't have to fiddle with wires so much. I'm only using RX, TX, reset, 5V, and GND and the 6th wire will be unused. Any advise on how to wire the pins to the cable or just go with what feels good?
