Arc Dimmer – Schematic

I finally found some spare time to upload the schematic for the Arc Dimmer:

Everything should be straightforward so I’m just going to give you a few notes on the optional components. If you want to build a stand-alone dimmer which is controlled via buttons and/or potentiometers, place components R36-R39, C30-C31 and D30-D31. If you want to build an I2C bus-controlled dimmer, place components U30 and R30-R35 (with the exception of R32/R33). U40 and U41 are there just to provide different footprints on the PCB.

PDF version of the schematic can be found on the Projects page.
