I’m interested in using APM 2.5 IO-s for steering my rover from obstacles. Idea is to use a second controller like Arduino Nano that can handle all the sensors and just send signals when something is in the way of the rover. I want to use multiple sensors but as I understand rover can manage currently only 2 ultrasonic sensors. I want to use array of low cost ultrasonic sensors and maybe some IR sensors.
How can I connect these IO-s ? How to activate it? Can I use the current firmware or do I need to change it. Should I use Python scripts or how?
Thanks In Advance,
