Hi,
This is a follow on of my previous thread "Control a RC plane with a joystick".
The code is pretty much the same, but that time, the App is controlling an ESP8266 board.
The firmware of this board directly drives up to 8 RC servos
So you can control almost any RC system (servos, brushless motors, ...) for less than 5$
The ESP8266 exposes its own wifi hotspot on which the phone can connect.
Transmission is done in real time thanks to the speed of UDP protocol.
Alternatively the ESP can connect on your home wifi network.
This App wouldn't have been possible without BA4 community and specially @wonder generic gamepad library. Thanks
Here is a video with only 3 servos (no more in stock !)
I have tested this configuration with a range of more than 50m in open air conditions. You can find ESP8266 with a "physical" antenna, range should be even better (3dB more, twice more range ?)
