What is inside a video game controller? Students learn about simple circuits and switches as they build arcade controllers using a cardboard box and a MaKey MaKey—an electronic tool and toy that enables users to connect everyday objects to computer programs. Each group uses a joystick and two big push button arcade buttons to make the controller. They follow provided schematics to wire, test and use their controllers—exploring the functionality of the controllers by playing simple computer games like Tetris and Pac-Man. Many instructional photos, a cutting diagram and a wiring schematic are included.
Students control small electric motors with Arduino microcontrollers to make simple sticky-note …
Students control small electric motors with Arduino microcontrollers to make simple sticky-note spinning fans and then explore other variations of basic motor systems. Through this exercise, students create circuits that include transistors acting as switches. They alter and experiment with given basic motor code, learning about the Arduino analogWrite command and pulse width modulation (PWM). Students learn the motor system nuances that enable them to create their own motor-controlled projects. They are challenged to make their motor systems respond to temperature or light, to control speed with knob or soft potentiometers, and/or make their motors go in reverse (using a motor driver shield or an H-bridge). Electric motors are used extensively in industrial and consumer products and the fundamental principles that students learn can be applied to motors of all shapes and sizes.

After reading the story "Dear Mr. Henshaw" by Beverly Cleary, student groups create alarm systems to protect something in the classroom, just as the main character Leigh does to protect his lunchbox from thieves. Students learn about alarms and use their creativity to devise multi-step alarm systems to protect their lockers, desk, pets or classroom door. Note: This activity can also be done without reading the Cleary book.
Computer-controlled servos enable industrial robots to manufacture everything from vehicles to smartphones. …
Computer-controlled servos enable industrial robots to manufacture everything from vehicles to smartphones. For this maker challenge, students control a simple servo arm by sending commands with their computers to Arduinos using the serial communication protocol. This exercise walks students through the (sometimes) unintuitive nuances of this protocol, so by the end they can directly control the servo position with the computer. Once students master the serial protocol, they are ready to build some suggested interactive projects using the computer or “cut the cord” and get started with wireless Bluetooth or XBee communication.

This book will teach you how to make graphical computer games in the Python programming language using the Pygame library.This book assumes you know a little bit about Python or programming in general. If you don’t know how to program, you can learn by downloading the free book "Invent Your Own Computer Games with Python" from http://inventwithpython.com. Or you can jump right into this book and mostly pick it up along the way. This book is for the intermediate programmer who has learned what variables and loops are, but now wants to know, "What do actual game programs look like?" There was a long gap after I first learned programming but didn’t really know how to use that skill to make something cool. It’s my hope that the games in this book will give you enough ideas about how programs work to provide a foundation to implement your own games.

Students create large-scale models of microfluidic devices using a process similar to that of the PDMS and plasma bonding that is used in the creation of lab-on-a-chip devices. They use disposable foam plates, plastic bendable straws and gelatin dessert mix. After the molds have hardened overnight, they use plastic syringes to inject their model devices with colored fluid to test various flow rates. From what they learn, students are able to answer the challenge question presented in lesson 1 of this unit by writing individual explanation statements.

As a weighted plastic egg is dropped into a tub of flour, students see the effect that different heights and masses of the same object have on the overall energy of that object while observing a classic example of potential (stored) energy transferred to kinetic energy (motion). The plastic egg's mass is altered by adding pennies inside it. Because the egg's shape remains constant, and only the mass and height are varied, students can directly visualize how these factors influence the amounts of energy that the eggs carry for each experiment, verified by measurement of the resulting impact craters. Students learn the equations for kinetic and potential energy and then make predictions about the depths of the resulting craters for drops of different masses and heights. They collect and graph their data, comparing it to their predictions, and verifying the relationships described by the equations. This classroom demonstration is also suitable as a small group activity.

The goal of this maker challenge is to demystify sensors, in particular the ambient light sensor, and to map its readings visually. In today’s world, we make sense of the environment around us by filling it with sensors, and we use output devices to display real-time data in a meaningful way. Take any smartphone as an example. Aside from the embedded camera and microphone, a number of other sensors collect a wide range of data. Depending upon the model, these sensors may collect data on proximity, motion, ambient light, moisture, compass, and touch. Some of these data are directly visualized through an app, while many operate internally and without a user interface, just below the surface of the screen. In order to become more familiar with the technology that we use (and often take for granted) on a daily basis, your challenge is to assemble a light sensor circuit, observe its readings using the Arduino Serial Monitor, and then create your own unique visualization by interfacing with the Processing software. Students learn how to use calibration and smoothing to capture a better picture of the data. Afterwards, they share their visualizations with the entire class. The time required for this challenge depends on students’ prior knowledge of Arduino and Processing software. Background resources for beginners help students get up to speed on microcontroller hardware and offer additional challenges for intermediate and advanced users.

Students apply sound-activated light-up EL wire to create personalized light-up clothing outfits. During the project, students become familiar with the components, code and logic to complete circuits and employ their imaginations to real-world applications of technology. Acting as if they are engineers, students are challenged to incorporate electroluminescent wire to regular clothing to make attention-getting safety clothing for joggers and cyclists. Luminescent EL wire stays cool, making it ideal to sew into wearable projects. They use the SparkFun sound detector and the EL sequencer circuit board to flash the EL wire to the rhythm of ambient sound, such as music, clapping, talking—or roadway traffic sounds! The combination of sensors, microcontrollers and EL wire enables a wide range of feedback and control options.

Focusing on the emperors Augustus and Nero, this course investigates the ways in which Roman emperors used art, architecture, coinage and other media to create and project an image of themselves, the ways in which the surviving literary sources from the Roman period reinforced or subverted that image, and the ways in which both phenomena have contributed to post-classical perceptions of Roman emperors. Material studied will include the art, architecture, and coinage of Augustan and Neronian Rome, the works of Suetonius and Tacitus, and modern representations of the emperors such as those found in I, Claudius and Quo Vadis.

Graph theory is a visual way to represent relationships between objects. One of the simplest uses of graph theory is a family tree that shows how different people are related. Another application is social networks like Facebook, where a network of "friends" and their "friends" can be represented using graphs. Students learn and apply concepts and methods of graph theory to analyze data for different relationships such as friendships and physical proximity. They are asked about relationships between people and how those relationships can be illustrated. As part of the lesson, students are challenged to find the social graph of their friends. This prepares students for the associated activity during which they simulate and analyze the spread of disease using graph theory by assuming close proximity to an infected individual causes the disease to spread.
