I have an issue with my Arduino pro mini. Yesterday, I uploaded a sketch a few times on the pro mini, with an FTDI adapter, and everything worked fine. Today I'm trying to reupload a sketch, but now, for some obscure reasons, my arduino pro mini doesn't want to reset itself, I need to manually reset it. Since it is embedded in some case, I can't do that if I want to upload a sketch.
- EDIT: I managed to make some tests, and it would seem that the DTR pin on the mini, doesn't work anymore. When I short the DTR PIN to GND, the mini doesn't reset itself. I believe that could be a reason. But why ? And how ? It was working a day ago.
I soldered the FTDI like that, and it didn't work several times. (At the moment I left it unsoldered because I don't want to solder it yet) :
Can anyone complete my intuition ?
Thanks in advance
