Good evening to everybody.
I built a powerful strobe with COB LEDs using an Arduino Nano. Everything worked flawlessly until the day I connect a wrong pin and burned the Nano. So I ordered an other pack and decided to use one as ISP for the ATtiny85 and use this one for the strobe.
I followed this tutorial:
but nothing worked.
So I tried to load the sketch again on the new Arduino but since then nothing works anymore.
I tried to follow all the suggestion found in the forum: chose the correct board, chose the old bootloader, chose the right USB port, chose AVRISP mkII, try another USB port, try another Arduino, install the last version of the IDE, install the driver for the CH340, restart the macbook.
Nothing.
Part of the error message is the following:
Using Port : /dev/cu.wchusbserial1420
Using Programmer : arduino
Overriding Baud Rate : 19200
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00
I'm very frustrated.
Thank you
