This repository will hold all the home-works/projects for the course New Human Factors in Computing - SUNY SBU Spring '17. Click on any of the assignmentsAssignment Doodles - Problem Statement:
Construct a circuit with at least one LED.
Document it with Fritzing (+ circuit diagram), as well as photographs, circuit diagram.
Create a page for it on your website and upload the images and text.
Since you're working in a team - only one person can do the uploading and the other person needs to link to it from their own page.
Calculate and write down the Voltage (Volts), Resistance (Ohms) and Current (Amps) in the circuit. Advanced hackers can even build a voltmeter using their Arduino to verify their calculations... :) (https://blog.udemy.com/arduino-voltmeter/)
Code a program that drives the LED to ‘write in space’, when using your phone’s camera to look at it.
Move the phone (or the arduino & breadboard) in space and see the “writing” in the photo. Will work best in low light without using flash - long exposure image.
The "painting" can be very simple. Just a dotted line, which is basically the LED going on and off in a loop, is probably OK. You are encouraged to go further, add an LED or two and create a nicer pattern that conveys more information, even text! (with say 4 LEDs)
Basically all you need to know about driving LEDs is here: https://learn.adafruit.com/all-about-leds?view=all
