Green Screen Pop Quiz

Circuit: comes from root word circle, goes around and around, electricity flows like water. Requires the following 3 things: power (- & +), conductor, load. Without a load, you've got a short circuit! Your Arduino board: There are several parts on the Arduino board, the most important parts that you will need to be familiar with right now are: 1. USB port: This is where you plug the usb cord in to connect the board to your computer, this is how you upload your code and it will also provide power to your board. 2. Barrel Jack: This is to provide power to your board from a wall wart (ac adapter) after you upload your code, you probably don't want it tethered to your computer anymore. You can use 5v, 9v, 12v to power your Arduino. An onboard voltage regulator will keep the board at 5v for you. 3. Reset button: This will start your code from the beginning, it does not delete or change your code. The only way to do that is to upload new code via USB. 4. LED indicators: One shows that the board is getting power, one shows when the board is receiving data (code is being uploaded), another shows when data is being transmitted (a program is running) and pin on is attached to pin 13 to test HELLO WORLD sketch (you can make it blink). 5. the pins: The little pin holes are where you can stick your jumper wires to create a circuit, different pins serve different purposes. Here are the basics: a. 5v & 3v - these pins provide power out from the Arduino to your circuit, one provides 3 volts and the other provides 5 volts. Think of this as the positive power source for your circuit. b. gnd pins - these are the ground pins. Everything that has power going into it, needs a place for that power to return. That point of return is know as ground, earth, or the negative that compliments the positive. c. vin pin - power can go in here (5-12v) instead of the barrel jack or USB port and power can also come out here (5v). It goes both ways! Useful to permanently solder on a battery port or other power supply. d. input/output pins: all of these pins can be used for input (information coming in from sensors) or output (information going out to actuators). there are 2 main types: analog and digital. What's the difference between analog and digital on Arduino? analog pins are labeled A0, A1, A2.... through A5 digital pins are simply labeled 1, 2, 3, 4, 5... through 13 But what's the difference? HINT: Analog: Think of analog as a gray area, a spectrum of possibilities. Very On, kinda on, sorta on, maybe on, a little on, mostly off, very off Max, hi, med hi, med, med lo, lo, min, off 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc…. Examples? Digital: Think of digital is black and white, one way or the other with nothing between. On or off Hi or lo 0 or 10 Examples? Breadboard: A breadboard holds your components with ease, otherwise you would have a mess of twisting wires and things would be constantly falling apart. Breadboard are for prototyping before you solder to a more permanent board. This is how the connections are made on a breadboard: Hook GND to the blue or negative line, hook 5v to the red or positive line, and use the green lines in the middle to make connections between components. Some other basic components: Jumper wires: used to make connections from between components, boards, etc. LED: light emitting diode, a diode that emits light! Servo motor: sweeps 180 degrees, back and forth (where does this exist?) DC motor: spins 360 at various speeds (where do we see these used?) Stepper motor: spins 360 in precise, singular steps... (where do we see this?) Resistor: resists electricity to prevent certain parts from overheating and burning out (don't let the magic smoke out!) Switches: digital or analog component? turns circuit on and off Potentiometer: digital or analog component? a turnable knob that allows you to turn the power up and down on a gray scale. Where does this exist in real life? Power source: battery, wall warts, usb plug.. provides power to your circuit. We will be using 3 kits for this pop quiz, Sparkfun inventor's kit version 1&2 as well as the Elegoo knock of kits (for more advanced users). The spark fun inventors kit will literally let you know exactly where to plug everything in with an easy to follow, visual map. It also provided the code for you! Guide with maps: https://cdn.sparkfun.com/datasheets/Kits/SFE03-0012-SIK.Guide-300dpi-01.pdf downloadable code: https://www.sparkfun.com/sikcode Arduino IDE: This is the Arduino software that you will use to program your Arduino. You will not need to write any of your own code for this class (you can if you want). You will mostly copy, paste and add little edits to preexisting code to make your programs. A piece of Arduino code is called a sketch. Here is the most basic sketch, popularly known as "Hello World" or "Blink." void setup() //sets up the sketch { pinMode(13, OUTPUT); //this assigns pin 13 as an output, not an input } void loop() //starts the loop that will run continuously until you make it stop. { digitalWrite(13, HIGH); //Turn on the LED delay(1000); // Wait for one second digitalWrite(13, LOW); // Turn off the LED delay(1000); // Wait for one second } POP QUIZ: 1. 5 pts. Download arduino on your computer: https://www.arduino.cc/en/Main/Software 2. 5 pts. Complete the Hello World, or Blink sketch 3. 5 pts. edit the blink sketch to change the way the LED blinks. 4. 10 pts. Complete a more complicated sketch using at least 1 sensor (input) and 1 other actuator (not an LED). *If you already have extensive experience with Arduino, you may opt out of this quiz and get your 25 pts. by helping your fellow students. YOU MUST GET APPROVAL FROM ME!! YOU MUST BE HELPING, YOU WILL NOT GET CREDIT IF YOU SIT! This helps me a lot! I can only help 1 person at at time, so... THANK YOU!

In order to earn all 25 points, you must complete the following tasks: 1. 5 pts. - Download the free demo version of Mad Mapper on your laptop. Set up an extended desktop (un-mirror display) so you have 2 screens, 1 on your laptop to work from, and the other to the projector to display your work. 2. 5 pts. - Make a grid of at least 4 videos in VDMX or Resolume. 3. 5 pts. - Set up at least 4 midi controlled, and 2 clock controlled effects in VDMX. 4. 5 pts. - Syphon main VDMX output with 4 video grid from one software into another (from VDMX to MadMapper). 5. 5pts. - Pick some objects from around the classroom (I brought some). Map at least 4 surfaces with each of the 4 videos from your grid. You may use the wall, but for only 1 of the 4 surfaces. You must use a variety of shapes, including 1organic (non-geometric) shape using mesh warping. I will be around to help you achieve all of these tasks.

An example of projection mapping a large building, house or structure. Projection mapping a car? Projection mapping a painting. Projection mapping an choreography, moving objects. Performance based, using body as object. Projection mapping as a indoor, custom installation. Projection mapping on unexpected objects. Assignment guidelines: For this project you will create a performance based projection mapping project. It can be any size (physically) and can be indoor/outdoor but should meet the following requirements: 1. Must be no less than 2 minutes in duration, can be as long as you like but if it exceeds 5 minutes we may not have time to watch the entire thing. 2. Must include live performative actions: moving objects, living performers, live effects (using VDMX, Resolume or other software, midi controls, etc.) You can use anything else you can justify as "performance." 3. Must use a minimum of 4 videos. Can either be your own videos, or appropriated from the internet or other sources. 4. Must have a concise theme that is communicated clearly using visual literacy. Use visual/auditory symbols to articulate the intended meaning. What are you trying to say with your performance and how will your audience understand your idea? How are you getting your point across? Will we guess it correctly in critique? Tips: *Projection is best picked up on white of very light materials. *With our license (VDMX) you can build files and save them on the classroom computers, and open them on your laptop with free demo version. *Practice your performance before hand to get your timing right. *Don't overthink it, simple is fine if your message is being communicated clearly. *Visually pleasing is good, but only half of the story... *Try many different objects, project inside them, outside them, play with surfaces. Some objects to consider: buckets, toys, boxes, sculptures, people, kitchen utensils, clay, posters, flags, wigs, feathers, costumes, mannequins, books, cages, vases, jars, cups, buildings with interesting surfaces, styrofoam, plastic, fish tank, canvas, and any of a wide variety of unique objects you can find at thrift stores, in dumpsters, etc. Play! Try new and scary things! Take positive risks! Experiment! Questions?
