Temp & humidity taken through the DHT22 where readings are received by the serial monitor AND a 20x4 LCD.

Temperature in Celsius and humidity readings are taken by a DHT22 sensor with the data wire attached to sensor's pin 2nd from the left to Arduino's pin 6. Readings are received by the standard serial monitor AND a 20x4 LCD. The LCD has a 10 ohm resistor set on pin 2 and an adjustable potentiometer attached to pin 3.

The setup was wired and tested performing reliably.
