Hardware and software requirements

For this project, you will of course need an ESP8266 chip. As for most of this book, I used the Adafruit Huzzah ESP8266 module, but any ESP8266 module will work fine here.

For the first project of this chapter, you will need an LED, along with a 330 Ohm resistor. You will also need a mini push button and a 1K Ohm resistor.

For the second project of this chapter, you will need a relay, a 10K Ohm resistor, and a small photocell.

You will also need a 3.3V/5V FTDI USB module to program the ESP8266 chip.

Finally, you will also need some jumper wires and a breadboard.

This is a list of all the components that will be used in this chapter:
