In the last tutorial we saw how to use the Arduino ESP32 AWS IOT library to configure an AWS client to subscribe/publish to a topic/thing. At the end of the tutorial we logged the temperature and humidity using DTH11 sensor.

In this tutorial we will see how to control the ESP32 pins using the AWS IOT. For this we will be using the Hornbill_IO library. Hornbill_IO currently supports the below four operation which will be extended in the near future.

  1. digitalRead
  2. digitalWrite
  3. analogRead
  4. analogWrite

We have a specific protocol/json format defined for this:
