Controlling DMX lamps with Pure Data through Arduino (pt. 1)
Why people recommend it
Shows an Arduino driving a DMX light via the DmxSimple library with no RS-485 driver chip or shield; one viewer found it simple, others asked how it works.
Watch for: Skipping the RS-485 driver may not work on every board
In their words
I recently saw this video where the creator controlled a DMX light via the Arduino.
