Web5 Nov 2024 · One thing to consider is that a pull-down likely means you are running power to a button rather than ground. Typically ground is more likely to be found around the … WebWith AVRs, we read a pin using it's PINx register and we write to a pin using it's PORTx register. We need to write to the button register to enable the pull-ups. For the LED we only need to use the PORT register to write to, however, we also need the data direction register (DDR) as the I/O pins are setup as inputs by default. hepatitis b recent news 2018
