Midi
Original Concept
The left container of the dish would hold Q-touches for midi single note sounds. The MIDI tones would be an eight note scale. The tones could be "played" with the longer tunes being accessed by the CD player controlled by Q-touches on the right dish.
Troubleshooting
Pollie:
Over the Thanksgiving weekend, Olivia and I were able to get the MIDI to play from multiple ports and respond to the q-touches. We worked on selecting notes for the MIDI frequency using the chart found on borg.com MIDI Note Number to Frequency Conversion Chart
Olivia worked on finalizing MIDI and had to wait for Q-Touch sensor to arrive to test multiple switches. She also worked on building a sample board to be the model to solder the perforated board.The MIDI stop responding to the Q-touch sensors,We eventually, realized the connections were on the wrong port. However, time had run out and MIDI had to be shelved.
Olivia:
The MIDI stop responding to the Q-touch sensors, partly because that we borrowed sensors from different people and some of the sensors didn't function in certain ports.I should have tested them all with LEDs. It wasn't later in Sunday, when the same problem came out that I realized that it is not the circuit, but the sensor's problem.It works in the opposite way, and it did't respond to certain ports. Anyway, we found the way to use them well in our LEDs, just writing an opposite code.
Talk about our midi, I started wiring things up and getting midi to work one week before thanksgiving, things were going well when I worked with Pollie to further hooking up midi to touch sensor. It was out of my expectation when it stoped working on Saurday. Pollie suggested that it's because of something's wrong with the circuit, because we all have the impression that it's usually minor problems that influence the functionality. What's more tricky, the wrong port worked once in a while, without thinking too much, I was just crazy swiching wires, chips, and breadboards. Saturday night, I tried to switch from midi to freakout command, it doesn't worked well. It wasn't the next day that I found both the sensors and the ports are wrong.
Even though I found my stupid mistake early on Sunday, and even thought we already have everything ready to test and use it, because we already run out of time switching the circuit to perforated board, Pollie made a sensible decision to just drop the midi part and get our project done in time.
Overall, I'm glad to see at least the CD player working, and I finally learned the importance of controling every element that is involved.Thanks for everyone's effort.
