The big space control
Contents |
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)
- Cover for the big electrical cabinet (jaroslav)
Thanks to all who have contributed hardware!
What we need
- More electrical cable

Schematic
The schematic to control just one lamp.
Relay layout
This layout is identical to the actual layout in the cabinet. Drawing coming soon.

Wiring 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 |
INPUT UTP cable
It's the one with the GREY tape!
This cable feeds signals from the Arduino to the relays .1
| 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 |
OUTPUT UTP cable
It's the one with the RED tape!
This cable gives the Arduino feedback about the state of the relays.
| 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 |
Power UTP cable
| Pin # | Color | Function | Notes |
|---|---|---|---|
| 1 | Green | Ground | |
| 2 | Green / White | Ground | |
| 3 | Orange | Ground | |
| 4 | Orange / White | Ground | |
| 5 | Blue | +24VDC | |
| 6 | Blue / White | +24VDC | |
| 7 | Brown | +5VDC | |
| 8 | Brown / White | +5VDC |
