ESP8266 is a low-cost serial to Wi-Fi module that is very popular among
electronics hobbyists. It can be used to connect a microcontroller to internet
over Wi-Fi. The things you can do with it are numerous. You could monitor and
log various sensor data like atmospheric pressure, temperature and humidity
together with geo locations on websites like thingspeak.com. Or you could
retrieve information from internet such as weather, number of subscribers on
YouTube, send tweets with your microcontroller, send email notification if your
plants get dry, etc.

Cheap and powerful 50 cents microcontroller | EFM8 Family
This is a step-by-step tutorial on how to setup and program an
EFM8BB10F8G-A microcontroller or any other EFM8 Busy Bee microcontroller family
from Silicon Labs. It is assumed that the reader knows the C programming language and basics about microcontrollers.
Why
would you want to learn to use
another microcontroller when there are many tutorials and libraries on
popular MCU's such as AVR and PIC? Well, because they are much more
cheaper but performant nonetheless - on Farnell you can buy them for
less than 50 cents - and also are pre-programed with a bootloader making
easy to program them using any USB to serial converter. Compare that
to Attiny13A which is around the same price but with half the pin count,
less speed and peripherals. Just see the features bellow.
