I’m experimenting with my first “breadboard arduino” (I own a Uno and a Nano but need a lower power setup for a new project).
I bought some components on ebay (this) and wired it all together on a breadboard. Please see attachment for a picture of the wiring.
When I plug my FTDI programmer (3.3V) to my macbook via the mini USB port, the power led flashes a couple of times (I suppose it’s the bootloading stage) then flashes solid red indefinitely. Now when I try uploading a simple “Blink” program with the arduino IDE, the power LED (pin 13) immediately fades, and does not blink anymore. The Arduino IDE tells me that “avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x00”
If I unplug the FTDI from the macbook, wait a few seconds, and plug it again, the bootloading stage starts again until the LED is solid red. So it seems clear that the sketch is never uploaded.
I have configured the Arduino IDE with:
- “Arduino Pro or Pro Mini”
- ATMega328 (3.3V, 8Mhz)
- port is /dev/tty.usbserial-A50285BI
I tried uploading from a Windows 7 computer, and got the exact same result.
After scratching my head for a few days and having checked the wiring multiple times, I’m a bit at a loss as to what I can do to make it work. Any help would be appreciated.
