Hardware and software requirements

Let's now see the required components 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.

You will also need an OLED display for the project. I used a 128x64 pixels monochrome OLED display, using the SSD1306 driver, which is the only one I know to be compatible with the ESP8266:

For the last part of the project, I used two LEDs, one red and one green, along with 330 Ohm resistors.

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 project:
