GPIO communication with Arduino

Robotics & Edge Computing Jetson Systems Jetson Nano

Hello,
I want to communicate Jetson Nano with Arduino using GPIO.

I want to send outputs from Jetson (as HIGH/LOW outputs) to Arduino, can any one help me at this?

I tried to use the samples on LED, and it works fine. but when I connect to Arduino and check the input value(s), it keeps printing “0” which means it can’t detect any output from Jetson (aka no pins are connected).

Probably your Arduino is working at a different voltage level, if I am not mistaken it works at 5V in general, whereas the Nano works a 3.3 voltage level, that’s probably the problem. The output from the Nano is not able to trigger the input on the Arduino.
