Introduction to the control circuit principle:

The circuit is mainly composed of power supply part, data decoding part and switch control part. The 220V AC is connected to the incoming line terminal, and after the step-down rectification circuit, a DC voltage is formed, which provides a working current for the circuit and provides working power for the circuit. After the DC voltage is stabilized by the three-terminal voltage stabilizing integrated circuit, a constant working voltage is output at its output terminal, which is used as the working power supply of the LED. Normally, the digital I/O port of the control IC outputs a low level, and the relay is disconnected. When the switch (hardware switch or software switch) is closed, a high level signal is input to the digital I/O port of the control IC as a switch signal. The control IC outputs a periodic square wave signal, so that the LED light turns on and off and makes periodic color changes.
