The Circuit

The RFID module is connected to the microcontroller as in Chapter 3. Connect the microcontroller to the PowerSwitch Tails as shown in Figure 4-2:

First PowerSwitch Tail
  • “1: +in” to Arduino digital pin 2

  • “2: -in” to breadboard ground

Second PowerSwitch Tail
  • “1: +in” to Arduino digital pin 3

  • “2: -in” to breadboard ground

Warning

This project controls high-voltage, high-current alternating current. Even though the PowerSwitch Tail is designed to make this safe, you should take extra care when wiring or rewiring the circuits for this project. Make sure everything is wired correctly and mounted securely before you plug either the Arduino or the PowerSwitch Tails in.
