In older times, only humans were considered smart, but as time passes, we humans keep making things around us smart as well to ease our lives. One such thing that is trending nowadays is a Smart home. Everyone wants their home to be smart and when we talk about smart homes the first thing that comes to our minds is a Smart Plug. A Smart Plug is basically a small adaptor that can be plugged into a regular electrical wall outlet but the difference is that it has the capability of connecting to Wifi and by the virtue of this any device or appliance that is plugged into the smart plug adaptor can be turned on or off by using a smartphone.
Smart plugs make it easy to automate and control small appliances and devices in your home. So today we are going to build a Smart Plug of our own. It may seem a lengthy and difficult task but actually, it is not, All thanks to the Tuya IoT Platform and Tuya Sandwich Evaluation Kit which made it easy for us to customize and build smart home appliances of our own.
So, Today we will get an insight into what's inside a Tuya Sandwich Evaluation Kit. After that, we will build a smart plug of our own using this kit and at the end, we will look check out a Fingerbot by Adaprox which is also built on the Tuya IoT Platform. It is going to be a lot of fun so let's jump into it.

Tuya IoT Platform and Tuya Sandwich Evaluation Kit
Tuya IoT Platform is a powerful platform with the help of which brands, developers, retailers, and manufacturers can directly tap into the AIoT/Smart Home opportunity and quickly grow their smart products. There is a wide range of products and appliances on this platform that can be built and customized. There are some pre-built products as well which are based on the Tuya Platform and can prove to be very useful in our daily life. You can access the Tuya IoT Platform from here but before using it you need to create an account on this Platform.
Having talked about the Tuya IoT Platform, Let's have a closer look at the Sandwich evaluation kit. Tuya builds a stable and sophisticated development board based on Arduino specifications. Tuya Sandwich Evaluation Kit as its name suggests is like a sandwich, assembled layer by layer, which allows you to quickly implement a complete IoT product prototype. Based on the Arduino open-source ecosystem, any open device can be connected to the Tuya Cloud Platform through the Tuya cloud modules of various communication protocols such as Zigbee, BLE, Wi-Fi, and NB-IoT. It allows you to explore more possibilities in the IoT field.
The main components of a Tuya Sandwich Evaluation Kit are as follows:-
Master control board: The master control board conforms to the Arduino interface (such as Arduino UNO and ST Nucleo). The master control board works as MCU and can be quickly connected to the communication board through Tuya MCU SDK to access the Tuya Cloud Platform.
Communication board: The wireless communication board provides various networking capabilities for the master control board. The Wi-Fi communication board with voice capabilities supports local far-field voice wake-up, online speech recognition, and device control.
Function Board: The function board provides substantial peripheral functions for the Evaluation Kit, such as sensors and actuators.
Power board: The Power board provides stable and continuous electricity for the development kit to strengthen the power supply capability of the master control board. It can also output different electrical levels for device debugging.
The Programs that we need to upload to the Tuya Sandwich development board can be written and uploaded using Arduino IDE. So, this is was a brief introduction about the Tuya IoT Platform and the Tuya Sandwich evaluation kit. You can read about the kit in detail from here and here.
