Raspberry Pi Pico Pressure Monitoring

I’m blocked from modifying this project because your current access is view-only; editing requires owner/editor permission or a fork you can edit.
What I found:
- The current project is a 2-pad LED part project, not an application schematic yet.
- The Flux library has a usable Raspberry Pi Pico 2 W part.
- A generic 2-terminal FSR sensor part was not available, so I would model each FSR as a variable resistor / external 2-pin sensor header.
Recommended schematic architecture:
- Pico 2 W powered by USB through its onboard micro-USB.
- Use Pico 3V3 as the excitation rail for all six FSR dividers.
- Each FSR channel:
3V3 → FSR → ADC node → 10kΩ resistor → GND- ADC node goes to Pico ADC input.
- Pico 2 W only exposes 3 external ADC-capable GPIOs: GPIO26, GPIO27, GPIO28. For 6 FSRs, add an analog multiplexer such as 74HC4051 / CD4051 or use an external ADC such as MCP3008.
- Best schematic choice: MCP3008 8-channel SPI ADC, giving six analog inputs cleanly and leaving room for expansion.
- Firmware/dashboard:
- Sample all six sensors every 30 seconds.
- Store last 20 readings in RAM.
- Host a web dashboard over Wi-Fi showing current pressure/voltage, a 20-row table, plots, and a Download CSV button for the current session.
To proceed, give me edit access or fork the project into one you can edit, then I can build the schematic directly.
Use MCP3008
Make editable fork
