Before getting in to deep of IoT projects & its implementation i would like to give some idea on what are the common IoT devices which i used & can be used from your end for home automation's.
As you know sensor is a major component of IoT , you can refer my post on IoT sensors to get details on the same.
I would like to talk about ESP8266 Node MCU, Raspberry Pi & Arduino boards in this section which is easily available & can do lot of automation's with simple Python or Arduino IDE.
NodeMCU is an open source IoT platform developed by ESP8266 Opensource Community runs Operating system XTOS. Node MCU is a SOC (System on Chip)with integrated WiFi and widely used in IoT.
Pin details are below

Raspberry pi projects kindly refer my post http://www.thetips4you.com/iot-projects-or-internet-of-things-projects/ for details.
Arduino is an open-source electronics platform based on easy-to-use hardware and software. It's intended for anyone making interactive projects. Arduino board uses variety of microprocessors and controllers, they have digital pins which are used to connect to devices, breadboard. Arduino provides its own integrated development environment to do the coding & push to the hardware.
The common one used is Arduino Uno. If you need other features like WiFi, bluetooth etc, you need to get additional Arduino shield and attach to the board.
You can also see in the market there are lot of readily available home IoT devices, which you can buy & use with out any modifications. Lets see some of those.
