I am the proud owner of an uBotino board by Robot-x. I do not own a USB-to-Arduino cable (FTDI with auto-reset). However, I do own computers with good old fashioned serial ports.
So I think I'm gonna build a serial programming circuit. Would the classic "Picaxe" level-correcting schematic work in this case?
* a voltage divider to shift down the signal from my PC from ca 11V to 5V;
* a series resistor in both data lines to limit current;
