Trying to build a scoreboard, with some 7-segment displays that will be on separate circuits, and this is what I plan on using for a circuit
I'll have a 16 MHz crystal between pins 9 and 10, then caps connecting to ground.
Pins 7 (VCC) and 20 (VCCA) are connected to 5 volts, then 2 caps then to ground
Pin 21 (AREF) is connected to a cap, then to ground.
Does this sound about right?
**** All the resistors connected to the ULNs and the two at the bottom are to give me places to hook up the oversized 7-segment displays on the PCB. Some of the extra resistors hooked up to the analog pins are going to be switches as well. Again, just to give me some holes to solder wires into for the PCB.
