Running water lamp_1.0

Overview

Working principle: Adjust the potentiometer to change the square wave duty cycle of NE555, and adjust the speed of the running water lamp.

Working voltage: 3~5v

Copper network: GND

Pay attention to the positive and negative of the power supply. There is no reverse connection protection. The negative terminal is connected to the negative terminal of the capacitor, and the positive terminal is connected to the positive terminal of the capacitor.
