Lesson 4: When in doubt, make sure your wires are connected

After spending an absurd amount of time trying to figure out why I wasn't gettting input from my FPR, I discovered the the wire I was using to connect it to ground had come loose. The lesson as always, I'm an idiot.

Lesson 5: Make sure you have the tech for the idea

Due too a city wide shortage of resistors, I was only able to get one FPS sesor for my project. Unfortunately, I eventually discovered the FPS I had much too sensitive for what I had hoped to accomplish. I used bubble wrap to insulate it, but it's still not everything I dreamed it could be.

Result: Hand Shake Test

Using a FPS, I created a Hand Shake Test. Using analog input, the test will show you not only if your hand shake is too hard or too soft, but it also displays analog out put to let the user know how much off they are.

I took a FPS, wrapped it in bubble wrap, and then taped it to a manikin hand. The FPS then sends data to the ardunio, letting it know how hard or soft the hand is being squeezed.

Once the input it read, the code determines if the pressure is too hard, too soft, or just right. Each of these are ranges, so the LEDs display analog data of how of from the ideal pressue you are. The Red Light indicates too hard or "Death Grip", the Green indicates "Just Right", and yellow indicates "Dead Fish."

For example, if you have the exact right pressure, the green light will go on. However, if you are way too hard, only the red light will go on. If you're close to the right pressure, but a bit too hard, both the red light and the green light will be on, both more dim then when they are on alone.
