Improvement of the sound and light controlled delay switch circuit
Source: InternetPublisher:王达业 Keywords: Delay switch circuit Updated: 2024/08/16
The original circuit diagram of the sound and light control delay switch circuit is shown in the figure above. After analysis, it is believed that there are three problems in the control circuit power supply circuit, sound detection circuit, and delay control circuit. The modified circuit diagram is shown in the figure below.
