USB night light

Overview

A night light based on esp8266, controlled using lighting technology.

The development boards I made before (see: https://www.oshwhub.com/blueskyer/ji-yu8266ex-di-kai-fa-xiao-ban
) were too many to use up, so I made a few simple ones USB lamp, using plug-in LED is to get rid of the dusty components in hand.

If you want to reduce the size, you can use esp12F and SMD LED. Place the esp12F and the main circuit on the front, and the SMD LED circuit on the back. In this way, the size can be about the same as a USB flash drive.

20211104 update, in order to make it look better, a 3D printed shell is used. See the attachment for the shell file.

Use M3*8 screws to fix it, no copper posts are needed.

About IIC general reading and writing program
I have been studying the reading and writing of IIC bus recently. Taking 24LC64 as an example, I wrote a Verilog routine. There is no problem with byte reading and writing or page reading and writing.
