Chapter 20. Temperature Indicator (with Processing)
Here’s an awesome project that allows you to quickly check the temperature of the environment using a few electronic components. This temperature indicator uses a small electronic sensor called a thermistor, which changes its resistance—the way electricity flows through it—depending on the temperature. The electronic components to build this gadget are shown in the Parts List. The Temperature Indicator is shown in Figure 20-1.
Parts List
- Arduino microcontroller
- MakerShield kit
- R1: thermistor (green or black candy drop electronic component)
- R2: 10KΩ resistor (brown, black, orange stripes)
- USB cable
- LED1: red LED
