Sound reactive leds without arduino

Hello, today i will show you how you can make your own high sensitivity sound/music reactive led strip without using arduino ;

MATERIALS REQUIRED

Sound sensorhttps://quartzcomponents.com/products/lm393-sound-sensor-module?_pos=474&_sid=50a0bf1fc&_ss=r

Irfz44n Mosfet https://quartzcomponents.com/products/irfz44-n-channel-mosfet?_pos=641&_sid=50a0bf1fc&_ss=r

10k ohm resistor https://quartzcomponents.com/products/10k-ohm-1-4-watt-resistor-with-1-tolerance-pack-of-10?_pos=196&_sid=50a0bf1fc&_ss=r

470ohm resistor https://quartzcomponents.com/products/470-ohm-1-4-watt-resistor-with-1-tolerance-pack-of-10?_pos=206&_sid=50a0bf1fc&_ss=r

12v power supply

Circuit connections

1 - connect the gate of mosfet to digital/out pin of sound sensor .

2 - connect the source pin of mosfet to gnd (ground) pin of sound sensor.

3 - connect the 10k ohm resistor between gate and source of mosfet.

4 - connect the 470ohm resistor to the vcc pin of sound sensor.

5 - connect the negative pin of power supply to the source of mosfet.

6 - connect the negative pin of led to drain of mosfet.

7 - connect the positive pin of led to the positive of power supply.

8 - connect the positive pin of power supply to the 470ohm resistor.

9 - turn on the power supply and adjust the sensitivity of the sound sensor by turning the

potentiometer in it.

10 - make some sound to test it.
