I am a self taught beginner. I have put together a doorbell type circuit that I modified and messed around with til I got it to do what I wanted. My prototype works, but that doesn’t necessarily mean it’s correct, right?
Can anyone look at this and tell me if I have made any errors that might cause problems? before I solder it up.
Purpose of circuit: pressing a momentary pushbutton will activate either a flashing LED or, a flashing LED AND a beep from a buzzer depending on the position of the power switch.
Example here:
When the button is pressed momentarily, the LED flasher (a special flasher with built in resistor and flasher) will flash approximately 5 times, but will flash continuously when button is pressed continuously.
If the power switch selection is on LED/buzzer, the same as above will occur, but the buzzer will only beep one brief time whether the button is pressed once or continuously. The buzzer will reset after about 5 seconds so it can be triggered again.
Attached is the schematic.
