Hey

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.

What do you guys/girls think???

Any suggestions/comments are welcome

Thanks :)

If you can go from a tiny directly to USB HID, you should be able to do at least as much with a 328P.

I find it harder to express logic in English than in Code.
Sometimes an example says more than many times as many words.

How would your "Serial to USB Converter Board" work differently from a $3 USB to Serial cable?

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 :).

V-USB should give you the tools you need then.

You could use the converter John refers to, and glue/solder an Attiny85 on top of it, that would be compact !
