Designing Smart Chatbot with IoT for home automation with videos (Hindi & English)

In this project, we will be using ESP8266 12e manufactured by Lolin to make a Chatbot that can control our home applications. To chat with our chatbot, we will use Facebook messenger platform. Also, we will integrate some AI into our chatbot using Chatfuel. It will then be integrated with IFTTT and Adafruit IO. Adafruit IO is linked to our ESP8266 at the hardware side. In a gist, the output pins of ESP8266 ...

So, if you conti ...

I have in mind a new project and I want to use an small board, like the Arduino Nano board. This new project is battery powered (3,7V Li-Ion battery). After checking the schematics of the Arduino Nano, I see that the microcontroler is powered at 5V. Of course, I can unmount the linear regulator (U ...
