This article introduces a sound and light controlled delay circuit that is very suitable for students to experiment (see attached picture). The assembled product can be easily plugged into the living room for use. When you return home at night, the lights are on before you enter the house, which makes you feel warm and avoids the inconvenience of groping for the switch to turn on the light in the dark. It is very practical.
