555 signal light
Source: InternetPublisher:他们逼我做卧底 Keywords: NE555 oscillator circuit signal light circuit Updated: 2024/06/17
A signal light composed of NE555 can work normally without any debugging as long as the wiring is correct. Adjusting VR1 can change the flashing frequency. If you want to extend the flashing time, you can increase the capacity of C1. It should be noted that the transistor T1 should be well cooled.
