Weather Display

Visualize current weather data on an LC display

Weather Display
Good weather data is more extensive than what is displayed by low-cost desktop devices that show the air temperature, air pressure and relative humidity on a monochrome LCD along with the time. A modern microcontroller with suitable peripherals can now quickly fetch the relevant and current data from the Internet and present the results in color, along with a realistic weather forecast.
