Guitar-Tuner

Planned Team Work Schedule

Detect the correct tone from the guitar string
Read microphone input into the Circuit Playground
Detect which pitch the user is attempting to tune to
Determine whether the current pitch is sharp or flat
Communicate pitch information via Serial Port to a laptop as an initial proof of concept
Final goal: display pitch information directly on the OLED

Edy

Gerson & Charlie

Automatically turn the motor based on detected pitch (Gerson)
Synchronize motor movement to the relative pitch of each string
Design a method to activate the motor
- Holding a button
- Automatic activation via microphone input

Charlie

In the end our schedule ended up changing dramatically throughout the project. We simply met up when we were available and set goals dependant on the day. For example, we would schedule a meeting on simply learning how to turn on the display and work with making the microphone detect pitch. These meetings ended up being around 2-3 hours dependant on the task. There were times in which we were not able to finish the goal by the meeting so we would disperse and end up doing parts by ourselves. We have a fairly efficient workflow overall, however we did struggle a bit with scheduling things near the end due to underestimating certain tasks. Each of us ended up working on most of the components together, even more than expected.
Edy and Gerson focused a lot of the oled, Gerson with figuring how to turn it on alongside the functionality, while Edy worked a lot on the UI and Gerson helped create a lot of the initial states of our machine.
The group as a whole didn’t figure out whether to use the external microphone or the internal one from the circuit playground till near the end due to the difficulties of making it function with the current setup.
A lot of time near the end was spent combining the code from the components together to create two different sketches that functioned together without bugs.
