Create alternating flashing LED's with this 555 timer based LED flashing circuit. Perfect for warning sign or model railroad crossing signal.
This small and simple electronic circuit behaves like the flash lights that you see at dangerous corners where your driving or at a railroad. i.e. it has two LED's / lights that flashes in an alternating fashion. You can use any color LED's e.g. red LED's, green, LED's, yellow, orange, etc.
The circuit has only 6 components, and that's including the 2 LED's. The main part of the circuit is the venerable 555 timer IC. Is there any timing circuit that doesn't use the 555?Components:
- 1 x 555 Timer IC
- 1 x 33k Resistor
- 1 x 120k Resistor
- 1 x 1 µF (micro-Farad) Capacitor
- 2 x LED
Anyway... this is perfect if you want to experiment with the 555 timer, build a warning signal for a model railroad, or, well.... just about anything else that might required alternating flashing LED's
