Three-Digit Number on UNO R4 WiFi-LED-Matrix

When reading data from your sensors you normally print them to the Serial monitor or some kind of display. In case you are happy with three-digit figures, just use the built-in LED matrix.

The llibrary provided only supports values from 0 to 999. You easily can extend it to also print negative values form -1 to -99 or even floating-point numbers from 0.01 to 99.9
