List of Figures

Chapter 1. Bringing JavaScript and hardware together

Figure 1.1. Oh, the magical things in our world!

Figure 1.2. The automatic fan system needs to take input from a temperature sensor and manage the output of a motorized fan.

Figure 1.3. The automatic fan needs a brain. A popular option is a microcontroller, which combines a processor, memory, and I/O capabilities in a single package.

Figure 1.4. A rough schematic drawing showing how the fan’s inputs, outputs, and microcontroller are connected in a system with power and circuitry. Don’t stress out if the symbols are new to you—you’ll be learning about circuitry as we continue our journey.

Figure 1.5. Microcontroller-based development boards make it more convenient to connect ...
