How to Control Your Drone From a Computer

After reading my post about how I used my computer to fly a Cheerson CX-10 drone, several people have asked me if it is possible to control other drones in a similar way.  It is in fact pretty straightforward, and in some cases you can re-use exactly the same hardware that I used to control the Cheerson CX-10 – the Arduino UNO and the Addicore nRF24L01+ Wireless Kit .

Component Description
Arduino Microcontroller Board Arduino UNO R3 Board Module With DIP ATmega328P(Blue)
Nordic Semiconductor 2.4GHz Wireless Card Addicore nRF24L01+ Wireless AddiKit with Socket Adapter Boards and Jumper Wires

It turns out that a large number of toy drones use the same nRF24L01+ compatible RF chips.  The word compatible is necessary because most of them seem to not use the Nordic Semiconductor chipset, but rather something like the XN297 from Panchip.In the original Arduino code, the author made it possible to select the protocol by various combinations of the flight joysticks.  For my version, I hard-coded it to always select the Cheerson CX-10 Blue protocol (see line 366 of nRF24_multipro.ino), but left the rest of the code intact so you can easily modify the code to select one of the other drones on this list.

Here is the list of drones that can be controlled by making this small modifications to the Arduino code (taken from nrf24_multipro).

Another set of very popular toy drones such as the Hubsan X4 and Estes Proto-X series use the A7105 / XL7105 wireless modules instead of the nRF24L01+.  These can also be controlled by an Arduino Uno, and instructions and code can be found here.
