LED Lamp Incandescent Lamp DIY CD4011 Circuits Sound and Light Control Kit DIY Circuit Board Project Kits
Product Description
The major difference between this sound and light control switch kit and many kits can control all energy-saving lamps, incandescent lamps, LED lamps, etc. that use mains electricity. Convenient welding and installation, stable work, free of debugging. The circuit of this kit is simple, the effect is good after repeated experiments, the new components, the failure rate is low, and the quality exceeds many similar switches on the market. Product features: energy saving, long life, no contact, no sparks.
Module function
The light is off during the day, and when there is a sound (calling and clapping) at night, the light is on, and it will automatically turn off after a delay, which plays a role in saving electricity and convenient for control.

Reminder
Energy-saving lamps and incandescent lamps have better effects. Most of the problems of flickering and 100K resistance in parallel can be solved. Some LED lights have flickering and dimming problems, which cannot be solved by connecting 100K resistance in parallel. This is not suitable. This requires yourself Choose whether to buy it carefully, because you cannot return it after soldering. If there is a flickering or dim problem, you need to find a solution by yourself.
Installation Instructions
Circuit
The difference between the paper drawing kit and the paper drawing kit is that the former has an extra paper circuit diagram, s component list and other materials, which can be downloaded in the above address. There are component parameters printed on the board, and you can weld directly without looking at the drawings. Therefore, it is recommended that you choose a kit without paper drawings to save paper and everyone participates in environmental protection.
Welding and debugging
1. All components of this kit are brand new. Even so, it is recommended to use a multimeter to roughly measure the quality of each component before welding, so as to know what it is. 2. When welding, you need to weld non-polar RC components first. The resistors and diodes should be installed horizontally and close to the circuit board; do not install polar components such as electrolytic condenser microphones, rectifier diodes, thyristors and other components. On the contrary, otherwise the circuit will not work properly or even burn out the components. 3. The kit is powered by 220V, and measures need to be provided to prevent electric shock. Before power-on debugging, carefully check the soldered circuit board against the printed circuit diagram, and avoid wrong soldering, missing soldering, short-circuiting, and component collision. To avoid electric shock, the body cannot touch any part of the circuit board after power on. 4. When debugging this circuit, please cover the photoresistor tightly and pat the electret with your hand, then the light should be on; if the photoresistor is irradiated by light, re-pat the electret with your hand, the light will not turn on. It shows that the photoresistor is in good condition, and the kit is successfully made. If unsuccessful, please check carefully for false soldering errors and drag tin short circuits.
PCB board features
1. The pad is enlarged and sprayed with tin, which is easy to solder, and the pad is not easy to fall off after multiple soldering 2. It is not prone to spontaneous bending (referring to bending caused by non-manpower conditions), and poorer plates will bend with time and environmental changes 3. The impedance is more stable and reliable.
