Hal created a neat project by taking parts of my Wifi Radio project and repurposing them to do something completely different. His Standalone Weather Station changes the color of an LED based on the weather forecast for tomorrow. If temperatures are trending warmer, the color changes towards red. Colder – blue.
His project is very well documented and includes code for both the ATmega168-based circuit that drives the LED using PWM and the shell script on the router that communicates with Weather Underground to get the forecast.
Nice work, Hal!
