A user-friendly LCD interface provides real-time updates, while advanced features like live people count, scrolling name display, RFID-based access ... starting from the Arduino UNO. Digital Pin 11 ...

which is why it's called an "emissive" display technology. That difference leads to all kinds of picture-quality effects, some of which favor LCD (and QLED), but most of which favor OLED.

Fingerprint sensors, for example, have progressed to being embedded beneath the display; we've listed some of the best smartphones with in-display fingerprint sensors that unlock quickly.

An Arduino Uno (CH340G clone) reads temperature and humidity from a DHT11 sensor and computes 10+ environmental metrics (heat index, dew point, enthalpy, humidex, vapor pressures, etc.), outputting ...
