I want to create a serial to USB converter board that will work with my temperature sensor. Now I have programmed my arduino UNO board and the temp sensor works perfect. I use processing with the serial output data from the arduino board. Now I want to program a blank Atmega IC with my sketch so I dont have to use the dev kit the while time, that is not my issue, the issue I have is to take the serial data out from the atmega to the computer. my plan is to take TXD and RXD pins (Which is the serial output pins) to a FTDI chip and from the FTDI chip to a USB shield and the BAM I got myself a complete unit. Obviously it wont be as easy as I just said but I just want feedback on my idea.
It would be all on one pcb :), i know there is already cables like that for serial to USB conversion, but i want a compact system and probably the biggest reason is, I like to design my own stuff :).
