[Colorsilk Screen] Light-sensitive pen holder "From the Abyss"

Photosensitive Box

A very simple and fun circuit for beginners to learn.

The photosensitive circuit's LED light does not light up when the ambient light is strong , but it lights up when the ambient light is weak . The R2 photoresistor has small light intensity resistance and large light weak resistance to achieve a voltage division on the base level of the triode, thereby achieving the effect of controlling the on and off of the triode. The R1 test uses 24k brightness for the best brightness. You can replace it yourself to test the appropriate resistor voltage divider.

The feasibility of the circuit has been tested and the effect is good.

The entire circuit is on the bottom PCB (the silk screen is from Mitty in the Abyss)

The electricity on the bottom is connected to two adjacent PCBs through window soldering.

Even after the circuit is connected, the stability of the box is strengthened.

Windows are opened at the edges of the boards, and tin is used to connect the five boards together, making them stronger and more beautiful.

At the same time, the circuit is guided to the four boards on the side, realizing multi-board connection, so that the side lights can also be lit.
