For input devices assignment I chose to use a simple potentiometer, as I was planning to use potentiometers in my final project
I designed a simple board using Attiny1614, the board has space for attaching a potentiometer that connects to an analog pin on the microcontroller. I also added a Darlington pair array (ULN2003) to the board to use the same board for next week's assignment.
The board is designed using eagle CAD.
I programmed the board using an arduino uno board with pin 6 of arduino connected to the updi pin on the attiny board.
