DC dimmer circuit

The resistor shown as 10K in the schematic is actually 1K in the photo, but that doesn't matter. The wiring to the chip in the photo looks OK as far as it goes, assuming you have the chip the right way round (as it is upside down, I can't see which end has the pin 1 marking). Can you post a photo of the whole setup, so I can see how the chip is connected to the mosfet, Arduino and power supply?
