Test data collection from mic to laptop

[troyth]

The first technical step is to set up a microphone to connect through an Arduino using Johnny-Five to a laptop. This will resemble the example demo we did in Week 3 using a mic rather than a photoresistor.

Let me know who wants to take this on as a task and I'll be in touch soon with more information.

This is how you'll set it up:

1. create the package.json file in the top level of your repo that you can get from the week 3 demo
2. create a folder called lib and put the app.js file in there
3. add this line to your package.json file: "main": "lib/app",
4. alter the app.js file from the week 3 demo to use a microphone that you will treat as a simple analog sensor, then test it out on your laptop!

@jnquick can you take this one on? You have the Arduino background, so I think it would be good for you to tackle the first major programming hurdle. Once you get one mic connecting to a laptop, you can start to test how many mics can simultaneously feed to a laptop. @yz2428 can then port this to the Raspberry Pi, and you two can work to figure out the max number of mics per Raspberry Pi/Arduino setup, then you can work with @YifengWu to finalize the grid design for #2.

Cool?

Sounds good.

Yeah, @jnquick and I can figure out the Raspberry Pi/Arduino setup together. I'm very willing to assist with the programming and Arduino-mic hookup as well.

Hey we got one mic feeding to the console. They range of readings is fairly small, but I assume that has to do with the resistor we were using. I am hoping to procure more jumper cables and resistors early tomorrow, at which time we will work on getting multiple mics to record data. Is there a way to determine the correct spec for a resistor?
