Assignment 2 Blink Buildout

Make a device that flashes with a personality and helps it a long with a very little noise.

Student Learning Outcomes:

• Student will learn basic sketch (program) components.
• Student will begin to learn about Ohms law.
• Student will learn to use low power LED’s and simple ways to find values for the ballast resistor. Student will learn to wire a switch and begin to learn about types of switches.
• Student will practice soldering for electronics.
• Student will learn to consider timing as an aesthetic parameter.
• Student will learn to load libraries and use serial communication between a computer and their Arduino.
• Student will learn to wire an 8 ohm speaker (handout).
• Student will learn to install a library.
• Student will learn to create a function.
• Learn how to make the speaker make a sound and how to vary the sound.

Switches

Description of Assignment: Blink Build out With your Arduino as the controller build a lightweight light that flashes, pulses or something. It is important that the timing be not just lightly considered but seen as a crucial part of your design. Your device will operate on Lithium ion power pack.

It is suggested that you build into some very lightweight plastic device or container/ It could be anything. It could be a shampoo bottle with an interesting form or a very lightweight child's toy. It could be Tupperware®. It would probably be smart to get several identical objects so you can screw a few up. The light circuit must have a switch. The Arduino too must have a switch (the one on the battery case will work if it is accessible. Consider the personality of your light. Can you make it edgy, coy, nervous, assertive, scared? How should its appearance affect its timing? What color should the LED's be? This object should be a finished piece, even if simple, ready for display. I intend to display them in the hallway.
