Receive Waypoint information to Arduino from pixhawk

[Yugma_Gandhi]

Hello There
I wanted to receive waypoint information to Arduino when drone reaches to that waypoint so that I could control servo the same time when it reaches to that waypoint
note: Here I am planning to plot more than 30 waypoints and I wanted that for agricultural use

MAVLink and Arduino: step by step

MAVLink and Arduino by Juan Pedro López This is not a post on the details of MAVLink serial protocol. If you are interested on the protocol itself, you can read the fantastic post by Pedro Alburquerque: This post will be focused on my experience and practical use of MAVLink protocol on an on-board Arduino (Nano with ATmega328) that communicates with a Pixhawk flight controller (a clone one, v2.4.8). I am using the Arduino to control the lights of my drone (WS2812B leds) and the code you will…

This could all be done on board with scripting, https://ardupilot.org/copter/docs/common-lua-scripts.html

@iampete

all be done on board with scripting

this is certainly the best way, i always keep forgetting about it, need some of that scripting in my life

Isn’t there even a mission command to control a servo connected to the FC?

We are dealing with triggering of an automated event here when certain conditions met

If you must use an Arduino, I have an example of a working project: bitdog-io/restraining_bolt: Arduino software to monitor and restrain ArduPilot drones (github.com). It uses the MAVLINK library and requires too much memory for some basic Arduinos. I used a Teensy 4.1 and it works really well.
