Introduction

CTBot is a simple Arduino class to manage Telegram Bot on ESP8266/ESP32 platform. It relies on ArduinoJson library so, in order to use a CTBot object, you need to install the ArduinoJson library first (you can use library manager). You also need to install the ESP8266 Arduino Core and Library or the ESP32 Arduino Core and Library. Don't you know Telegram bots and how to setup one? Check this.
