| | Hi In this article we'll test out the PMS5003 sensor in order to see if it works. I've forgot to buy a connector board, so we will do a manual connection to the Raspberry Pi 3 B V2. This involves cutting the wires and adding some resistors. Please note that you need: 5 Jumper Wires 2 Resistors 10K Ohm Raspberry Pi Setup Before connecting the sensor to the Pi we need to configure the Pi for this usecase.

Adafruit Feather RP2040 with Music Maker FeatherWing - Will Haley
25.8 parsecs away

| The Adafruit Feather RP2040 is an Adafruit Feather device that uses the same processor as a Raspberry Pi Pico. The Adafruit Music Maker FeatherWing is an audio playback shield designed for Adafruit Feather devices. After soldering headers or otherwise wiring the two devices together Adafruit's sample code can be used to play audio files. I found the sample code did not work for me. A reddit thread highlights the unofficial Arduino-Pico library. Using that library in the Arduino IDE along with some adjustments from the Flashgamer website got things working for me.
