This simulation shows a classic 555 timer–based railroad crossing light flasher. The 555 IC is configured in astable mode, producing a continuous square wave at its output. The timing network formed by the resistors and the 10 µF capacitor controls the oscillation frequency, which matches the measured value of about 1.24 Hz, suitable for realistic warning light blinking. The output of the 555 alternates between high and low, driving two LED branches through steering diodes and current-limiting r
