The shopping list for tomorrow is found below.
- 110-120V AC aquarium pump, submersible
- 20-25 feet of plastic tubing
- household AC outlet, box, & cover
- relay (for using the 5V DC output to power the custom 110V AC outlet; we plan to ask employees for recommendations)
- battery adapter for powering the Arduino (most likely a 9V-to-barrel-plug mechanism)
The team is also looking into several different possibilities for creating the custom 110V outlet, one of which appears to involve powering the outlet directly through a wall wart, while still allowing the Arduino to operate as a control system.
A breadboard starter kit has been ordered and will arrive on Friday. In the meantime, Parm and Davina are currently learning how basic circuits work using breadboard simulators on the Internet. These simulators also provide the capability of programming a virtual Arduino with the virtual breadboard, which promises to prove very helpful.
