This project is based on the Fusion RH6616 ( product number: C78963 ) touch dimming chip. The initial idea was to make a small desk lamp, but considering that the desk lamp must be bright enough and look good enough, as a small and exquisite entry-level work, it is better to design one Night light.
I happened to buy a tube of brass wire and threw it in the corner. It seemed that it could be used as a support, so I left two holes in the PCB design to connect the two PCBs in a stack. It still looks good~
I designed a simple circuit based on the chip manual. Since the chip has three modes, I used the simplest three-level dimming mode here. As for other modes, you can try it yourself. The method is to connect the two pins of model1 and model2 to ground or high level to achieve different control methods. The corresponding relationship is shown in the figure below:
The lights under this project can choose other packages that are easy to weld, but if used as a night light, it is recommended to choose a warm-toned light source. If you choose the same lamp as me , be careful when soldering to avoid short circuits.

I wonder what your night light looks like? Share it in the comment area~
