I am powering my Pro Mini(3.3V version) using an external battery (~6.5V 700mA) . I used to connect it to the RAW and GND pins on my pro mini and everything ran fine.
Today when I powered up my Arduino again, it didn't light up. A quick glance told me that I had connected the battery to the RST and GND pins mistakenly. Quickly pulled them out and put them into place, the Arduino worked perfectly until I discovered that the RESET button is no longer working. Without the RESET button I can't upload anything to my board.
Tried connecting the RST and GND Pins, didn't work.
The board is working fine though, I discovered a new procedure to upload as follows-
NOTE: I use the USB-to-TTL adapter by DSUN (picked up at a local electronics store).
- Connect the RX, TX and GND Pins from the adapter to the Pro Mini.
(The green LED on the Pro Mini lights up dimly)
- Upload the sketch from the IDE.
- As soon as the IDE shows "Uploading", connect the +5V pin from the adapter to RAW pin on Pro Mini. Upload goes fine.
The above procedure is working just fine, and the board as well. But I'd like to have my RESET button back.
So what do I do?
