It transpires that folk have been busy writing ‘cores’ – the name for code that adapts Arduino code to run on different hardware – for several other bare chips, and some have 20 pins – plenty. Have ...

Ensure that the backpack pins are straight and fit in the LCD module, then solder in the first pin while keeping the backpack in the same plane with the LCD. Once you have finished the soldering work ...

So the TX and RX leds are driven by a couple of pins on the ATmega32U4 (see a comment on the hardware connection below) to make it look like they are on the serial bus. They were not intended to be ...
