SH-805 ASIC holiday lights

The SH-805 circuit serves as a holiday lights controller, as illustrated in Figure 2-64. It is similar to the SH-804 circuit board, although the pin locations and control functions differ. By pressing the SB button, users can select between HI to H4 light cycles that create a flower-like pattern.

The SH-805 circuit is designed for controlling holiday lighting with multiple operational modes. This controller features a microcontroller that manages the sequencing of lights, allowing for various patterns and cycles to enhance visual displays. The circuit board layout is optimized for user accessibility, with clearly defined pin locations that facilitate connections to the light strands.

The operational modes include a range of light sequences, which can be activated by the SB button. Each mode corresponds to a specific lighting pattern, with HI representing the highest intensity or speed of the light cycle, while H4 denotes a slower or more subdued effect. The flower-like cycle indicates a specific pattern where lights illuminate in a blooming effect, creating an aesthetically pleasing display.

The circuit incorporates resistors and capacitors that help regulate the current flowing to the lights, ensuring that they operate safely within their specified voltage ratings. Additionally, the use of transistors allows for the control of higher power loads, enabling the circuit to drive multiple light strings without overheating or failure.

For installation, connections are made through designated terminals on the circuit board, which are labeled for easy identification. Proper soldering techniques should be employed to ensure reliable connections. The circuit is designed to be powered by a standard AC supply, which is converted to the required DC voltage for the microcontroller and other components.

In summary, the SH-805 holiday lights controller is a versatile and user-friendly circuit designed to bring dynamic lighting effects to festive displays. Its various modes and robust design make it suitable for both residential and commercial applications, enhancing the overall ambiance during holiday seasons. Circuit SH-805 made holiday lights controller shown in Figure 2-64, it can be seen from Figure SH-804 circuit board of the same, but the pin locations manifold and control func tions different. Press the SB can choose HI ~ H4 lights cycle flower -like.
