I worked through the third basic project in the Arduino Starter Kit Projects Book. I like to write about the projects to reinforce my own understanding. The third project, the “Love-O-Meter”, creates a simple circuit with a temperature sensor. Using the Analog-to-Digital converter, the Arduino reads in the value coming from the temperature sensor, then lights up a combination of 3 LEDs depending on that value. Here’s what my circuit looked like:
