In my case, I will be using the +5V output. That’s all.Īs I am going to use some WS2812B led lights, I will be feeding them directly from the PDB (Power Distribution Board) of my drone. Just remember to connect RX on one side to TX of the other side and both GND together. No special requirements here, as both boards use UART interfaces. You only need to connect the serial port of your Arduino to the serial port of the Pixhawk. I am using the Arduino to control the lights of my drone (WS2812B leds) and the code you will see here is mainly focused in that direction. 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 learned to program C (C86, Microsoft C, Turbo C) 30 year ago (yes 1986), i’ve been away from programming in C, eventually only reading some code since then, and recently (2 month ago) I got to know arduino and its IDE… My background - I have been using Ardupilot software on Multirotors and airplanes for 1 year. This post result from my struggle to find information about the subject to understand the concept, and developing a basic concept test.
