Raspberry Pi Pico Pressure Monitoring

Worked for 27 sec

I’ll design the Pico 2 W + six-FSR monitoring schematic, including the analog front-end and the firmware/dashboard requirements. I’ll first check the existing project state and permissions, then wire and verify what can be changed.

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.
