Weather Plotter is an exploration in physical data visualization, computing, and mechanics. For the project I was interested in how I could document weather where ever I go. I developed both the mechanical components as well as the Arduino and Processing code. A GPS receiver records the location and sends the data to Processing, which in turn searches the current weather data using openweathermap.com. The data determines the speed of the motors and the rate in which ink is dispensed creating a unique visualization of the current weather conditions.
