SOUND WAVES

Idea: This project is still in work in progress but I wanted to share what I am currently doing.

Implement: I am interested in how signals/sensors so I chose to do this project as SONAR and RADAR technology has always interested me (PHYS 158, waves).

The sonar detector's job is to measure distances and look for objects in its immediate surroundings.

I want an understanding of the working ACTIVE SONAR works under water as well and how RADARs work.

To apply this:

RADAR: I will be making a radar system.
ACTIVE SONAR: understanding active Sonar and passive Sonar. Click this to know about active SONAR. Active sonar.

Parts Used

Assembly: After getting all the parts (Arduino kit) I started watching a lot of tutorials/projetcs related to SONAR sensors and radar systems.

Schematic: I have followed a general schematics from one of the videos, but I will be making some changes by adding a display section. Here is the project on the left.

After assembling all the parts together, this is how it worked. I also used the Ardruino IDE to write my code. I took help of some youtube tutorials for that as well.

After running it this is how it worked.

Since, the project is still in progress, I will be making a tower and what is the range of SONAR, how it can be increased/decreased.

This is me having fun with sonar+servo lol (From claw)

Output

Working: This works on a very similar to the claw sonar mechanism converting the signal to reading distance. Here are some videos that helped me to gain more knowledge on this topic.

Output: I used processing software to send an output using COM3 for a project involving a sonar sensor. High frequency sound waves are emitted by sonar sensors, which are used to detect objects nearby. The sensor can compute the separation between itself and an object based on the time it takes for the sound waves to return I programmed the processing software using a tutorial on youtube to display the distance using red lines in order to visually represent the data obtained from the sonar sensor. The sensor's distance from the object it detects is shown by the length of the lines. Longer lines show that the object is farther away, while shorter lines show that it is closer to the sensor.

Future plans?

Goals: I will be making the output 360 for that I will be using a different motor, and using a display to showcase the distance + insetad of these red lines, I will be using dots. I studied about SONAR for submarines and I wanna do something related to do bearing rates, but haven't figured out how.

What I learnt? + Other projects: I learnt about SONAR and RADAR and how complex the working actually is.

Other Projects that I have worked on: Created small electronic devices: Metal detector, water alarm circuit system, digital clock, controlled lighting system, number guessing circuit game, FM radio, and an automatic streetlight LED model which used LDRs. I do not have the schematics as these schematics were provided by the teacher at my high school. (I lost them : ( ). I also built circuits with resistors and capacitors (RC), sending waves as input from the function generator and reading them on the oscilloscope channels (output) (PHYS 159, very fun).
