DIY Breathing Light

Seeing that others have done breathing lights, I feel very good, so I decided to do one.The circuit diagram is found online, and the materials are collected by myself.

LM358

Transistor BC337

Resistance 100 ohms 47K 100K

Electrolytic capacitor 22 microfarad

Hole plate 3cm × 2cm piece

Wire soldering

This is my material

This is a simple power supply for my breathing light. Oh, I don’t want to waste the battery.

The corresponding electronic components are soldered to the universal board as shown in the circuit diagram. After soldering, the product panels are as shown in the figure.

Then look for materials to decorate, my base uses a plastic box

Waste utilization, use the things that are idle around, and an old bottle in the home can just be used.

Everything is assembled.

This is the display effect after doing a good job.
