» We have extra supplies if you're running low on batteries / jumper wires / resistors / LEDs. Just stop by office hours (or knock on 228B) and ask!
» We have lots of components available for you to play around with; feel free to grab 1 or 2 to tinker with, but please sign out whatever you take.
» If you want us to order components for your team's project, send us a list with < Name, Link to, and Price of > the components that you would like by 5:00pm this evening.

Announcements: Grading

» Project 2 Submissions have been graded; please pick them up in 228B (Feel free to disassemble graded work that you have picked up!)
» Project 2 Partner Feedback is due by 11:59pm today, Monday, 3/14

» Grades for Quiz 1 will be posted by 1:30 this afternoon. Quizzes can be viewed on virtual grade and will reflect your raw score. The average raw score was 80%. You may add 1 point to your raw score to get a sense of how your grade was put into our gradebooks. After the 'curve', the average was an 83.

Final Project

due5/5

We will be spending the remaining six weeks of this course building high-fidelity prototypes of wearable devices from the ground up. You now have enough base knowledge to design devices that include a small PCB component, an Arduino device (e.g., the Bean), and, potentially, an iOS/Mac program that links via Bluetooth. This is your opportunity to be creative and to have fun -- we want to see cool devices that people would enjoy if they were a commercial product.

Project 2

due3/7

In this project, you will be working with a “sonic motion sensor” (HC-SR04) that determines the distance from the sensor to an object that the sensor is pointed at. The range for the HC-SR04 is between 2 centimeters and 4 meters, giving a user a short-range distance measurement capability. Your projects will first be put together on a breadboard based on a circuit diagram that we provide to you below, and will provide distance information through the LightBlue Bean (see template below), which will then forward the data to either an iPhone application or a Mac OS X application (provided for you). Additional parts of the project will include mocking up your device in Fritzing in the breadboard and schematic view, and also soldering parts to a printed circuit board (PCB) that we have designed and had fabricated based on the schematic we have below. Finally, you will be tasked with designing a reasonable real-life use case for your device that can be used in the real world as a wearable.

due2/17

Go from idea to moderately challenging circuit, including both hardware and software. Develop a circuit that uses a shift register to set a particular number of output LEDs to values dependent on a program. The program itself will be up to you, but you must use a shift register and multiple LEDs, and you must write an Arduino sketch to light up the LEDs through the register.
