Interlude: Home Engineering from Requirements to Implementation
In this chapter, we are going to take a little break from the usual scheme of things so you can learn about various sensors and how to use them in your projects. We will use several new pieces of hardware: photoresistors and tilt, flex, FSR (force sensitive resistor), digital temperature and humidity, and temperature sensors. We will also use two new libraries to communicate with the temperature and humidity sensors: DHT22 (thanks to nethoncho) and the Wire library (thanks to the Arduino development team). These are all key parts in completing our hypothetical customer's request for a wireless temperature monitor that uses Bluetooth communication.
Note We will ...
