Flash the Firmware

Download the latest firmware from the link below.

Hold the BOOTSEL button on the RP2040 while plugging it into USB. It will appear as a USB drive on your computer. Drag the firmware .uf2 file onto the drive — it will reboot automatically and start running.

Once that's done just download the code from the src directory from the link below and drag the files onto the RP2040.

If everything is correct the eyes should appear and the touch sensor should make them turn into hearts.
