Really nice job. What exact model of arduino is the one you use?. You think that this one should do the job: http://articulo.mercadolibre.com.ar/MLA-630932149-arduino-uno-r3-cable-usb-_JM (I´m able to answer my own question here. That model seems to be ok: Arduino One R3) Seam to be that I´m going to have to learn arduino now (I´m too old for this craps) Oh, i have tried to open those captures on logic, on every posible system i find...and it still claims to not being able to open due to version isuess. No data on theyr website about this. Maybe you are able to upload the file again?
