Feb 6: Week 5 In-Class

build clean -if you were building half way and wanted to stop and start over

ctrl P - opens programs

• ex: PlatformIO:Build

Looking over lab

Changing Fahrenheit to Celcius

Code:

“float FTemp = (temperature x 1.8) + 32”

• will do order of operations but parentheses will help organize

• did it inside if statement right before it prints, final step change units

New Stuff

Template Repo

Found repo, create on in your acount and use all files in repo as starting point

HTMLs

Head and Body section

p5, javascript, layer on top of Javascript, so you dont have to use it on its own,

Javascript is to p5, as C++ is to PlatformIO

sketch.js is where the code we write will be

-default file on website indext.html

Relationship Between Files

index.html

-> referenceing style.css (file info and how you format page)

• content in html, css for style

-> ps.js (function that we use, ex: circle formula)

-> sketch.js (code that we wrote, ex:code to draw circle)

css is a way to format

function setup() vs draw()

setup- once when page loads

• if i want them to be used throughout and apply to all following functions

draw- over and over again, as many times it can, ~60 times a sec

• will only apply to the local functions

variable mouse x - mouse position

let- allows you to create variable

• ex: let x increase over time (x=x+1)

Browser Consol (ctrl+shift+J)

Hooking Up to Arduino

web serial.js needed to do serial stuff

bunch of serial functions used to serial stuff in sketch.js and serial.js

“InData”- input & organization of data

“Array”- variable with a list

• every program language has concept of array and ability to list
