I'm going to design the PAR meter Pcb to be as small as possible and power it off a standard 9v battery. I'll probably use the ATMEL328-AU, as I have 20 of them already flashed with the Arduino "Optiboot" - Bootloader. I'll include a connection for a FTDI adapter as it will be needed for the initial programming. If you could do me a favor- please post your wiring diagram with a little more info as it will save me some time. I need to know what size jack plug you want ( 1.8mm, 2.1mm, 2.5mm ect.) Also a copy of your "sketch", so that I can confirm the exact pin/wiring configuration used. I'll get to work on this and send you PM's if further questions arise.
