i have uploaded the adc voltage calibration sketch to atmega328p using arduino nano, however the microcontroller doesnt seem to do anything as seen on the pc serial monitor. where did i went wrong?
Which particular sketch are you trying? You can post that here. In the meantime, also make sure that you're selecting the correct baud rate. Due to baud rate mismatch it is very likely not to see the desired results in the serial monitor.
