dmxFogMachineArduino

Use cases

I use this to control my own fog machine, which does not have a dmx port. But a button. I connected a relay to this button, every time the channel 20 is active as an example, the relay gets turned on.

What do you need?

• 📋 An Arduino or something like an Arduino
• 📋 Some power source, like an old power adapter
• 📋 A "RS-485-Module", here is an link, to amazon
• 📋 A dmx (xlr) port, here is also a link, to amazon
• 📋 Optional an oled display and 3 buttons to set new dmx address and show some stats
• 📋 Some time and good soldering skills
• 📋 If you use a OLED display, google your SCK and SCL port for your arduino

You can find the pre configured ports here

Here is an wiring diagram

I hope you can read it. On the RS-485 Module, where DMX stands, there you have to connect the dmx pins A and B. The T stands for a button. The button and OLED display is not required but useful.

Here is an example soldered board

Not the best solder board but it is working

wiring basic without display

• GND => GND
• GND => RS-485 DI,DE,RE
• RX => RS-485 RO
• 5V => RS-485 VCC
• 5V => Relay VCC
• D11 => Relay EN
• GND => Relay GND

What will come next?

• 📝 New wiring diagram
• 📝 Clean up the code
