Give Your Pi Pico Captouch Inputs For All Your Music Needs
RP2040, unlike many modern microcontrollers, lacks a native capacitive touch peripheral. However, Jeremy Cook demonstrates in a lighthearted video that the usual software-driven approach works well, requiring only an external pullup resistor. For those interested in capacitive touch projects, Jeremy provides a KiCad schematic and PCB design in the video, enabling the addition of 23 capacitive touch sensing inputs to a Pi Pico. The board is mechanically flexible, easy to assemble, and retains the ability to use all pins as regular GPIOs.
The open-source board, showcased by Jeremy, offers versatility and can be easily assembled. It is also available on Tindie, catering to DIY enthusiasts and makers. Jeremy’s video features various musical creations and inventive ideas, including using old PCBs as capacitive touch sensors by utilizing copper fills as electrodes. One intriguing creation is a “macropad of macropads,” demonstrating the potential for unique and creative projects using capacitive touch sensing technology.
Overall, Jeremy’s video serves as a valuable resource for anyone interested in exploring capacitive touch projects with RP2040. The demonstration of the flexible PCB design and its integration with the Pi Pico opens up possibilities for inventive and interactive projects, making it a must-watch for makers and hobbyists alike. If you dont have the crocodile clips for this project, we have a few for you at PiShop.
