Week 5 Notes

February 6th Class Notes

Markdown Table Pretifier - VSC Extension, auto formats tables to make easier to read
Putting a Video in Markdown -

• link to video site
• short videos made into animated gif
• WedM - video file playable in HTML < video > tag

VS Code

• Build clean essentially cleard build queue
• Ctrl + Alt + P - search panel for all commands
• Can add parenthesis to math equation to make equation easier to read and make sure it is done in the correct order
• When building, terminal tells percentage of storage code uses on chip

P5JS Intro

In Sketch:

• setup runs once when page loads
• draw runs as many times per second as possible
  • usually 60 times per second
• console.log (variable) - prints variable in console of browser
  • access console with Ctrl + Shft + J

Hooking P5JS To Arduino

Files

• add library p5.webserial.js
• add serialfunctions.js
  • all code can be in js
  • seperate files make it easier to read

Other Notes

• inData - incoming data as a number (variable)
• P5JS Webserial template available on github
  • Github Template
• if you have multiple incomming data, use an array
• incomingSerialData[#] - number in list of target data array
• Examples of P5JS

Makey Makey - an aurdiono that can pretend it is a keyboard

• uses compatible touch

February 7th Sensor Changes Lab Notes

Joystick - two potentiometers for x and y axis and a pushbutton switch

Connecting Joystick to Arduino

Joystick	Arduino
5v on joystick	5v on arduino
GND on joystick	GND on arduino
VRx on joystick	analog input A0 on arduino
VRy on joystick	anaolog input A1 on arduino
SW on joystick	digital input 3 on arduino

VRx - variable resistor, x-axis
VRy - variable resistory, y-axis
input_pullup - prevents the pin from floating and giving inconsitent high/low readings

February 8th Class Notes

On circut board - Q = transistor
stages- grouped components on a circut board that are related
our resistors are 1/4 watt
capacitors store charge
ac syncronous motor - microwaves

• uses ac power, can be plugged into wall
• dc moters will move opposite direction of leads are switched

continuity multi meter function - finds ground
input_pullup - adds resistor to prevent short in flating switch
debounce button - use software

surpluscenter.com - where we can buy larger components
VIN and GND pin on arduino do not go throught the voltage regulator

Power Supply Notations

On wall Plugs:

• DC out - how many volts? (#V) and what current can it supply (#A or #mA)
  • 
• type of plug charge
  • 
  • 
• switching power supply - turning on and off very quickly, regulated, has electronics, is also called a chopper
• Linear power supply - non-regulated, puts our more voltage than labeled, assmuming that the voltage will change depending on what is plugged in, only has transformer (no other electronics)
