We wanted to create a PCB that would respond to capacitive touch via the circular touchpads on the bottom on the PCB. A LED will light up when the corresponding touchpad is touched, which is detected through the ESP-32 placed in the middle of the PCB. In addition to the LED lighting up, it would also emit a sound from the attached speakers.
Ground plane only on non-touchpad areas in order to reduce parasitic capacitance
USB-C connection
ESP32-S2-SOLO and Arduino IDE compatibility
Approximately 10 inches in length
Early stages of our group soldering all of our components on our PCB in Supernode!
This was a very rewarding experience that taught all of the beginning processes of creating our own PCBs, from the designing process all the way to the actual manufacturing process. We also learned how time-consuming creating a fully functional PCB is and gained a new appreciation for the ones that are in our electronics. Finally, we also learned how detail-oriented we have to be since some parts are really similar to other parts with only some minor differences that turn out to be not so minor in the actual PCB.
