Humidity & Temp LCD Display Code

This document contains an Arduino sketch for measuring and displaying humidity and temperature using a DHT sensor and an LCD. It initializes the LCD, creates a custom degree symbol, and continuously reads data from the DHT sensor to display on the LCD. The program includes setup and loop functions to manage the display and sensor readings.
