    Autonomous AR Parrot Drone 2.0 Flying

    You can try the Parrot Bebop 1 or Parrot Bebop 2.Thanks!

    Looks like you aren't running the file in the directory/folder where you saved it. Before you run npm install ar-drone you need to get in to the directory where you installed .json. Your error indicated that npm install is looking for the .json file in the current directory.Thanks and good luck.

    I found one error with your code as I built your sun tracker. You have if statements between line 31 and 56. You write your if statements like this: if(photocell1Reading > photocell2Reading, photocell3Reading, photocell4Reading, photocell5Reading) (See image of this below). This doesn't throw any errors but it doesn't work (at least for me). All it did was move the servo to one side and then stop doing anything even why I shined flashlights on the sensors. I did a little research and found you have to write it like this: if(photocell1Reading > photocell2Reading && photocell1Reading > photocell3Reading && photocell1Reading > photocell4Reading && photocell1Reading > photocell5Reading) (See image of this below) Thanks for this great intructable.

    This is a fabulous project. Nice job explaining everything in detail. Great job! It was a good challenge being one of my first Arduino projects. Keep on making great intructables like this. Here are some photos of the one I built.

    Great instructions. Love it! Just one thing I wanted to mention to the community, your example program in step five doesn't work (for me at least). It is having the drone takeoff, immediately land (so fast that it doesn't even take off), then land again after a certain amount of time. I believe it should be:var arDrone = require('ar-drone');var client = arDrone.createClient();client.takeoff();client.after(5000, function() {this.land();});Thanks.

    Try this as your program. The program in the instructions is having the drone takeoff, immediately land (so fast that it doesn't even take off), then land again after a certain amount of time. I think there is just an error with the instructions.
