Hello Everyone, I cannot seem to send DMX with an Arduino Nano + max485 I'm using the DmxSimple library "FadeUp" example I believe my problem is with the wiring. I have a DMX lighting fixture for testing, and I have confirmed the fixture is working perfectly with DMX coming out of QLC+ on my lap…

Arduino Nano + MAX485 -- wiring for DMX output?

have a look at RS485 example
you need to use DE and RE to control the direction of transmission
I also find it useful to have a PC USB-RS485 dongle to monitor the bus
