What You Need

To build all the projects in this chapter, you need the parts you see in Figure 51, ​The parts you need​.

Figure 51. The parts you need

• A half-size breadboard

• A PIR sensor

• A TMP36 temperature sensor

• An MCP3008-I/P analog-to-digital converter

• Six female/male jumper wires

• Some wires

You already learned where you can get a breadboard and wires in ​What You Need​. Most of the vendors mentioned there also sell the two sensors and the MCP3008 chip. For example, Adafruit sells a PIR sensor (product ID 189), the TMP36 (product ID 165), and the MCP3008 (product ID 856). If you prefer the Parallax PIR sensor, make sure you’re ...
