15 Running Led Circuit Using 555. Output of the 555 astable is connected to the clock.the sequencing of the led is arranged. A 555 led flasher circuit uses an astable multivibrator which produces pulses for flashing the lamp.
The circuit can be used as a flashing metronome t.k. Creating flashing and fading led effects using ic 555 circuit. These series of pulses allow you to continuously blink an led, for example.

15 Running Led Circuit Using 555. An led chaser or led running light can be used as a decorative light, fancy light, chasing taillight for vehicles, etc. The first figure shows the basic configuration associated with 555 ics, here it is connected as an astable multivibrator. The resistors and the capacitor 1 uf can be experimented with to get different rates of blinking over the connected led. The 555 timer ic is an integrated circuit (chip) used in a variety of timer, delay, pulse generation, and oscillator applications.
