Hardware

As we mentioned in Chapter 1, Arduino and iOS – Platforms and Integration, we need a Wi-Fi shield (http://www.arduino.cc/en/Main/ArduinoWiFiShield) and a micro SD card formatted with FAT16 (take a look here for more details: http://www.arduino.cc/en/Reference/SDCardNotes). The SD card is used to permanently store the activation times when Arduino is powered off, so its size is not so important.

Additional electronics components

In this project we need some additional components:

  • Optoisolator MOC3041
  • 330 Ω resistor, 0.5 W
  • 330 Ω resistor, 0.25 W
  • Red LED
  • TRIAC BTA08-600

The TRIAC is capable of 8 Amperes RMS at 600 V, which is about 1700 watts at 220 V. You can use another TRIAC model of the same family (for example, BTA16) if you have a more powerful ...
