Introduction
583 RGB leds in 53x11 grid. Raspberry Pi Pico W (microcontroller), speaker with amplifier, two (2) I2C Stemma/qt sensor sockets (3 or 4 pin JST PH), a light sensor (phototransistor) facing front and nine (9) control buttons, a reset button, JST-PH battery connector.
Connecting
Programming
Raspberry Pi Pico can be programmed using Micropython or C/C++. This will deal only with MicroPython.
To upload your file to Pico, it need to be put into bootloader mode: hold down the bootsel button while plugging the USB cable: it should show up as a drive called RPI-RP2.
IDE's
- Thonny is the da facto
- VS Studio: MicroPico (the id is paulober.pico-w-go). If not found use this https://github.com/microsoft/vscode/issues/108147 because some Linux distros use OpenVSX.
Thonny
- Connect the USB cable while bootsel button is pressed: RPI-RP2 is found on device manager.
- Copy the pimoroni-galactic_unicorn-v1.20.6-micropython.uf2 to RPI-RP2.
- Start thonny; see the right down corner that correct device is connected.
- Program.
- Run/ Stop / Load.
