Arduino DMX-512 I/O Shield
Breadboard is Great and All, But it’s not going to survive a six week run with actors tripping over it and that kid’s show that runs on Sunday mornings. So here’s a shield that can fit onto your Arduino and securely hold all your connections in place. It is tested and working with the dmx reception software I wrote for the Arduino.
- Same hardware be used to receive or send DMX, so you only have to build one shield.
- Onboard termination switch.
- Reset switch brought to top of shield for easy access.
- Pin 13 LED brought to shield for status/error messages.
- Two tact switches allow in-the-field addressing, without permanently disabling any pins.
- Header sockets for easy prototyping.
- Solder through-holes for permanent installations.
Note: I changed the pin assignments slightly from early versions of the software to allow easier routing. Pins 3 and 4 in the software are now pins 2 and 3, respectively. As of Rev11 this change has been made, get the latest version here.
