Once you've got the IDE installed and libraries in place you can run our test sketch. This will check all the hardware, and display it on the screen, its sort of a universal test because every part is checked. It's also a great reference if you want to know how to read the light sensor or initialize the touch screen.
It's normal to get SD Card...Failed if there is no SD card in the socket.
The light sensor value ranges from 0 (dark) to 1023 (bright)
The temperature sensor will heat up if the backlight is on for a while, that's also normal! To avoid self-heating turn or or lower down the backlight brightness
D3 and D4 measure the analog voltages on the 3 pin JST connectors. They'll be floating until some voltage is applied to them.
You can download the ready-to-go UF2 file and drag it onto the bootloader drive. To enter the bootloader, double click the reset button.
