The big space control

Goals

  • Lights can be switched using a web interface and regular light switches.
  • Roofs can be opened and closed.
  • Redundant: if the Arduino fails, the light switches remain working.

Hardware

What we have available

  • A little under 100 industrial relays (Piet)
  • Industrial electricity cabinet (Piet)
  • Diodes and NPN heavy-duty switching transistors. (Koen)

Thanks to all who have contributed hardware!

What we need

  • More electrical cable

Schematic

The schematic to control just one lamp.

Schematic

Relay layout

this layout is identical to the actual layout in the cabinet.

Relay # Relay 00 Relay 01 Relay 10 Relay 11 Relay 20 Relay 21 Relay 30 Relay 31

Function Cell 2 Cell 3
Notes Cell B Cell C

Color Codes

Lesson learned: adding new colors on the fly will result in chaos:

Color Function Notes
Brow 220VAC L1
Grey 220VAC L1 switched for outputs
White 220VAC N
Blue +24VDC except immediately at main 220VAC input
Red +5VDC for Arduino inputs
Black Ground light switches switch ground
UTP cable I/O for Arduino

arduino INPUT UTP cable

It's the one with the YELLOW tape!

Pin # Color Function Notes
1 Green Relay 01 input
2 Green / White Relay 11 input
3 Orange Relay 21 input
4 Orange / White Relay 31 input
5 Blue Relay 41 input
6 Blue / White Relay 51 input
7 Brown Relay 61 input
8 Brown / White Relay 71 input

arduino OUTPUT UTP cable

It's the one with the RED tape!

Pin # Color Function Notes
1 Green Relay 00 output
2 Green / White Relay 10 output
3 Orange Relay 20 output
4 Orange / White none Will be connected to R30 input with resistor
5 Blue Relay 40 output
6 Blue / White Relay 50 output
7 Brown Relay 60 output
8 Brown / White Relay 70 output

Software

The software is identical to the one in the small Spacecontrol.
