Planning

My partners are Jinny and Lynn. We decided to work off of an early-stage lock that Jinny made out of three potentiometers. Here is a video of the original work that she made:

As a group we thought it would be interested to work off of this foundation. There was the obvious project that came up, which was to take Jinny's work so far and complete it: add green/red lights and sounds to indicate whether the correct combination was entered. Jinny and her partner in the above video tried to map values to the potentiometers but weren't successful, so one other task of our project would be to first map successfully "codes" onto the potentiometers.

However, as we were brainstorming, we had an idea of how to take this a step further. We thought that it would be fun if the outputting sounds were based on settings on the potentiometer, wherein each potentiometer's levels produce different tones. The goal for the user would be to get a single tone to come out of each of the potentiometer's values; otherwise, the three tones will be different.

We decided to start on the easier one first and then build off of it toward the more ambitious one.

Here is the user flow that we expect for the first one and the second one:

Here are the components of this plan that we'll have to build or use:

To do this plan:

• build a circuit to include:
  • 3 potentiometers
  • 1 red LED
  • 1 green LED
  • 1 pushbutton
  • 1 speaker
  • 1 Arduino
• write Arduino code which reads 3 potentiometer inputs which are sent to a button, verifies the inputs against some ranges, maps these to pre-determined values, then outputs 1 turns and 1 tone

However, our goal is to attempt a more ambitious project once we are able to successfully make Plan B. Here is Plan A, the one we hope we can make:

Here are the components of this plan that we'll have to build or use:

• build a circuit to include:
  • 3 potentiometers
  • 3 pushbuttons
  • 3 speakers
  • 1 Arduino
  • BONUS:
    • 1 red LED
    • 1 green LED
    • 1 more speaker
• write Arduino code which reads 3 potentiometer inputs independently which are sent to a 1 button each, verifies the inputs against some ranges, maps these to pre-determined values, then outputs 1 tone per speaker individually
