32 channel mains lamp controller [Project]
posted May 27 2014 23:02.37 by spic0m




Jaanus Kalde made this 32 channel light dimmer project, that is available at Github:

"I needed a computer controllable 32 channel light dimmer for an art installation. After looking around a bit I found out that there isn 19t even a Arduino shield for the work. So I made a quick 4 channel stackable board to control lights.
The board uses SHARP thyristor based solid state relays to switch mains voltage. As normal with thyristors 13 all the outputs can be used as dimmers through zero-crossing detection. All outputs are able to handle 0.9 A / 200 W. We connected 40 W incandescent light bulbs to it but you can control whatever with it 13 lights, electronics, computers, motors etc."
