ATtiny MCU’s have no hardware UART so you can not use the serial monitor out of the box.
In this video I will show 2 ways to enable serial.print for the Attiny85
I will use an ATtiny with the “Snapduino” bootloader that we made in the previous video, but it can also work with other ATtiny bootloaders.
