Since all the microcontrollers mentioned operate at 3.3V logic levels, connecting sensors that provide up to 5V directly to the analog inputs might damage the microcontroller. You should consider using voltage dividers or level shifters to scale down the sensor output voltage to a safe range (0 to 3.3V) before connecting it to the analog inputs. This ensures that the sensor’s signal is within the acceptable range for the microcontroller.
