In this example we use the DHT22 (or AM2302) humidity/temperature sensor and the Arduino UNO board to read data and print it out to the serial monitor. The DHT22 is better.
A light-dependent resistor is a light-controlled variable resistor. The resistance of a photoresistor decreases with increasing incident light intensity; in other words, it exhibits photoconductivity. A photoresistor can be applied.
These displays were used in old Nokia 5110 cell phones. It is a 84x48 pixel monochrome LCD display and you can use it for graphics, text or bitmaps. To use.
