I managed to delete my entire post earlier today, however, here is the process for my phone case!
I started with a concept sketch of the pattern I wanted to create. These are the materials I ended up using:
-Gray wool, leather, 1 Piezo electric disc, 1 blue LED, Arduino UNO board.
I started by testing out the pattern. I had never used to sewing machine and I knew it was going to be a challenge even though the pattern I drew up seemed simple enough. Getting straight lines in that machine was hard! I will continue to practice this skill for sure.
I used the code from the “Knock” example as a base. I changed the “threshold” and the “delay” in hopes that the Piezo sensor would become sensitive enough to detect the cel phone’s vibration. Regardless of the code ( that works) it seemed that the vibrations of the phone alone wouldn’t trigger the threshold to go above 1.
Go to my instagram to see a video of me tapping the cel phone-case like a crazy man.
Thank you : )
