Based on my experience doucmenting last week, I modified my set up significantly from last week. My camera is now mounted over my work. Here's what what looks like:

Here's what it looks like when I'm getting out supplies:

For this lab, I didn't run into any issues building this, EXCEPT that initially I couldn't get the connection between the computer and the Arduino to work at all. After some time of trying all kinds of software fixes, I realized that the issue was that I was using a bad micro-USB cable. Turns out only some of the transfer data.

Also ran into no issues with the lab.

This is the first exercise so far where the code isn't included. Here's the critical part of the code I wrote:

int in = analogRead(A0);

int out = 255 - map(in, 0, 10, 0, 255);
if (out < 0) {
  out = 0;
}

analogWrite(ledPin, out);

I had to experiment a bit to get a useful relationship between the input and output values. I chose to invert the relationship, turning the device into a night-light!

Force-sensing resistors

Pretty straightforward.
