Audio Running Lights Circuit - Engineering Projects
https://bestengineeringprojects.com/audio-running-lights/
Here is a project for audio running lights circuit which uses filament bulbs instead of LEDs. The circuit employs seven channel darlington array IC ULN2004 and seven reversed biased zener diodes having different breakdown voltages. At low audio level, zener diodes having low breakdown voltages will conduct and corresponding lamps will light up.

1) Insert the NPN transistor into the breadboard so that the 3 different pins are in separate columns. 2) Using a jumper wire, connect the emitter pin to ground. 3) Reorient the LED so that the negative leg is connected to the collector pin. 4) Connect a jumper wire to the base pin. (we will use this for our audio signal later)

We have created 4 different LED Running Lights Circuits using very simple components. In the first circuit, we have implemented a Flashing LEDs with the help of transistor based Astable Multivibrator. The second circuit uses Chasing LEDs and is based on IC CD4017. In this case, the LEDs just turn on one by one in a consecutive order.

D1 lights with the output of N1 at high and N4 low. This process is repeated with one at first, then two, then one LED is lit again. An impression of running and flashing light is generated with light patterns shifting to one place at every step. The unused gates of this 3 LED chaser circuit should be connected to the positive or negative supply rail.
