Hello all! This instructable happens to be part 3 of my ESP series where I continue to experiment and explore the various features of the ESP 8266-01 board. In the first and second part of the series I have mentioned the wonderful capability of this little board to support I2C communication and also interfaced the ESP board with multiple I2C devices.
You can read more about these features in the previous parts:
Part 1:
Part 2:…
In this part of the series, we will look at the possibility of extending the GPIO pins of the ESP8266 and also control the pins using IoT!
For IoT integration we will be using the Blynk application which is quite simple to integrate with IoT projects.
Let’s get ahead with this instructable!”
