I have working Arduino IDE on Mac, successfully programmed the boot loader onto the Pro Mini 3v/8MHz.
However, I get an error when trying to upload the sketch to the Pro Mini using the same programmer.
The programmer is the Adafruit USPtinyISP.
Error message: avrdude: stk500_recv(): programmer is not responding
I desperately need to get this programmed, no idea what is causing the issue???
