Librabry to controll Dji Tello

As there was no library available to control the Tello DJI drone by nodemcu or by Arduino, there was only 1 library founded, but even that was not working, so i have created a library from the scratch.

Installation

Download, This library(tello) either by zip or by git. Then in arduino library go to sketch -> include lib -> add zip lib.

or

just simply download the file, copy tello file, and then add the tello file in Arduino library, >located in Document -> Arduino -> Library

Then add the tello file in Arduino library, located in Document -> Arduino -> Library.

Usage

This library includes a class "Tello"

• First, make an object of the class Tello

  Tello tello;

• Then you call init function to initialize it. In setup loop

  void setup(){
      .....
      tello.init();
  }

• Then for take-off simply call takeoff

  tello.takeoff();

• And for landing

  tello.land();

And of course Dillinger itself is open source with a [public repository][dill] on GitHub.

Demo

you can use, demo file to test it. it will takeoff the, the drone then after 5 sec, land it, then repeat after 10 sec.
