Step 2: Classify Inputs and Outputs

Picture of Classify Inputs and Outputs

Next, classify the project’s inputs and outputs. A weather monitor might have a temperature and humidity sensor and a display of some kind. Internet projects might have a cloud service as an input, output, or both, like my Internet Valentine project which also has a button input and LED and vibrating motor outputs for each circuit. The project I’m building today is a prop passkey evaluator that uses a membrane keypad input and outputs to an alphanumeric display as well as three indicator LEDs.

You have given some really good advice in the video, things I have had to learn (usually the hard way) over years of programming. Thank you!
