This is pretty cool and shows how versatile the 555 timer is. I believe the 555 is providing the trigger pulses, and the "ping' may be timed by the capacitors. Are you able to provide a basic overview of how the circuit works?
Okay. But instead, I would like to turn this HCSR04 module into a microphone that is very sensitive to noise changes and be able to detect who is whispering at night since I have neighbors who live respectively adjacent to my house. I am definitely looking for a comforting result. Responding to my post is NOT a crime. :) Hi.
@@estechknowledge The same as the diagram in the description, but no worries, I changed my project, I'll use an LDR (light-depending-resistor) for my circuit. I was going to do a proximity sensor like those used in a car when going in reverse that it beeps the closer you get. However, I tried to use the HC SR04 without an arduino, but it would have been hard, so I won't use it anymore. I'll use an LDR and make a circuit that when you take an item (Indiana Jones style) from a platform, a loud sound is produced.
I like your videos, but watch them on mute. I have almost mistaken your channel for some of those trashy fake free energy/lifehack junks. You have great potential just please please don't use that music.

How is that possible
Can you show the diagram
That is amazing
It is available in the video description.
@@estechknowledge
Thank uou
Fanstastic work 👏👌 thanks my friend👍
you lieing this circut didn't working with me
What component should I replace if I want to change the range of the device to like specifically 3 or 6 feet?
Increase the R1 value.
I appreciate it kind sir
Fantastic idea -very good.

Amazing video! What is the frequency and duty cycle of the NE555 output?
Sorry I don't have any oscilloscope to measure.
Can we seperate it into two different devices ( i mean the transmitter and receiver seperate) wirb two circuit diagram.
can u tell me where did u connect the battery's positive and negative???
Diagram is available in the video description
Sir isme range ko kaise control kare
can I measure range with this circuit without arduino? thank you for response
pin 4 of ic 555 not tied up with pin 8 why?
Can we do this project without PCB
why is my circuit connected to a source, the light continues to come on and the sensor doesn't respond if it is blocked
led wont turn on and i notice the gdrive file is different from the one in the video?
Can I connect it to DC motor?
Can I add speaker instead of LED?
Do you mean buzzer
Good ideai...make hand wash tap
Can I use 741 IC instead of NE55 IC
No
@@estechknowledge ok
40th like bro🤜
What is the maximum distance it can sence
About 2 feet
For some reason, mine is always on and doesn't turn off ever.
What are the resistor you have used?

How to changing the distance
where can i see the circuit diagram?
In the video description
Creative video, thanks for sharing :)
Parabéns, muito obrigado.
No circuit diagram
Circuit is at the description below
Bom dia parabens
Super, pourriez-vous nous donner le schéma de montage ?
Very cool montage! Like and subscribe from me. Good luck to you!
THANK YOU
PLEASE SEND ME schéma de montage
Available in the video description
Your not teaching but showing of
Obrigado amigo, fiz o meu o funcionou bem.
y el esquema electrico ?-
En la descripcion del video.

can we use motor instead of light?
Instead of an LED, use a transistor to drive the motor.
Can I use buzzer instead of LED?
Offcourse
