Lesson 9 - xyzen/CS490 GitHub Wiki

In this lesson, we learned to use inputs from the raspberry pi, in the form of a sensor and button, to control outputs to the raspberry pi, and also to track and visualize data in node-red dashboard. Since the DHT11 was not available, I used a BME280 temperature, humidity, and pressure sensor instead. Installation instructions for the node-red library used to interface with the BME280 can be found here. Note: This requires automatic loading of the I2C kernel module to be enabled on the raspberry pi.
