Arduino Project 2 Spaceship Interface

for input: digital = binary = high/low

digital pins act as inputs and outputs

learned about the resistor bands, takes some getting used to, a video would probably be the best way but I looked at the diagrams for the ohms just use digits for all but the last band, and last will multiply. there is also a band that represents tolerance and some other things

you set pin modes (input or output) on the setup function
