Assignment 10A _Push Buttons

https://www.youtube.com/watch?v=Ab6Lca6MGD8&feature=youtu.be

/*
  Button
 
 Turns on and off a light emitting diode(LED) connected to digital  
 pin 13, when pressing a pushbutton attached to pin 7. 
 
 
 The circuit:
 * LED attached from pin 13 to ground 
 * pushbutton attached to pin 2 from +5V
 * 10K resistor attached to pin 2 from ground
 
 * Note: on most Arduinos there is already an LED on the board
 attached to pin 13.

Assignment-10B : Potentiometers

/*
  Analog Input
 Demonstrates analog input by reading an analog sensor on analog pin 0 and
 turning on and off a light emitting diode(LED)  connected to digital pin 13. 
 The amount of time the LED will be on and off depends on
 the value obtained by analogRead(). 
 
 The circuit:
 * Potentiometer attached to analog input 0
 * center pin of the potentiometer to the analog pin
 * one side pin (either one) to ground
 * the other side pin to +5V
 * LED anode (long leg) attached to digital output 13
 * LED cathode (short leg) attached to ground
 
 * Note: because most Arduinos have a built-in LED attached 
 to pin 13 on the board, the LED is optional.

Looking Outwards: Sensors and Shields

Adafruit Color Sensors

I found this particular sensor to be extremely exciting because I am really interested in color theory. One of the projects I was thinking of was a simple matching game when an individual would see a color on a screen, out of reach, and try and match that color exactly using an assortment of objects around them. I would also enjoy using this sensor for my own personal painting practice in order to discover interesting color combinations.

Flex Sensor 2.2

For this sensor, I thought it would be interesting in performance pieces. I really would enjoy being able to use the movements of my body to control sound and visuals. These would either have to be built into cloths or somehow hidden under makeup because I think it would be physically interesting to have someones face being able to control these elements as well and not just through a camera lens. I wounded how sensitive these sensors are.
