Found this about divide by 58: "The value of 58 or 58.2 is often seen in example code. It's worth exploring where this "magic" number comes from. The Echo high pulse duration represents the time for the first detected reflection. The speed of sound varies mainly with temperature and to a far lesser degree by humidity. The chirp travels to the target and is reflected back, its journey is twice as long as the distance. 58 represents an assumption that the speed of sound is 1000000 / 58 * 2 / 100 = 344.8 metres per second. 344.8m/s would equate to a 21.6 degrees Celsius (70.8 Fahrenheit), 40% relative humidity day."
Thank you for resolving this mystery, it makes a lot of sense now! It also explains the slight difference between the value in WOKWI emulator and my readings, as I have used the speed of sound value from wikipedia, which is a speed of sound in dry air at 20 °C = 343 m / s.
@@StigBSivertsen OK, I see. That´s actually the easy part for me since I´m doing this for so many years, but the programming side is what´s complicated and what I often struggle with.
The reason for 'Black = zero ' is the wires are coloured the same as the Resistor colour code, Black = 0 Brown = 1 ect. loads of people go 'oh yeah' when I point it out !! great video as usual !...cheers.
Yep, it makes a lot of sense... but - since the Logic application UI is dark, this channel is white in the app, so it´s not consistent anyway.. I would probably prefer the wire to be white as well. Anyway, thank you for your comment, I´m glad you like it!
Well done on yet another fantastic video Upir. I was so looking forward to this one and you have not not disappointed at all. The depth you cover is on another level and you make it super easy for anyone to follow along, never change the way you present these tutorials 🙌💪
@@upir_upir can you show how to add this parkingsensor to the "Arduino OLED Menu Tutorial" you just created, so that I can enter the parking sensor from the menue?
@@toroddlnning6806 Hopefully you should be able to just copy both sketches and paste it into one, and make some slight changes to the menu sketch - i.e., when on second screen, show the parking sensor. Let me know if you have any problems doing this and I can surely help.
This is such a cool project. Was looking for something like this for a 60’s Ford F100 project. Probably using e-ink display or (success depending) a diy electroluminescent display.
Thank you, Charlie! I would also like to see your project in case you go with the diy electroluminescent display. Sounds like something I would like to try as well if I had more time :)
@@upir_upir keep up the great work. The goal is to replicate the Apollo programs DSKY display but LumiLor paint is already being used elsewhere but doesn’t have the same look.
Awesome video, very instructive and well explained Thank you for your hard work. I have a question, i'm looking to build an 8 waterproof sensors system but there aren't enough input pins in the arduino to have 8 sensors. is there a work around to achieve this you can think of? Thanks again
Thank you for your comment. There are many ways how to solve your problem, but I guess the simplest one is to use Arduino MEGA. In many ways, it´s similar to UNO, but it has much more pins, probably more than you will ever need. Plus you can simulate it on WOKWI.
Amazing content. One question please. I got all the sensors feeding me the distance but I cannot get it displayed on oled screen. Is the wiring different if I'm using arduino leonardo?
Great project! I have implemented everything but when I run the program and check the serial monitor I get wrong distances for 1 or 2 of the 3 sensors. They are equally distanced apart on breadboard but still close. Could this be a problem? Is it that the trig pulses somehow mix with each other and cause the error? Is there a way that we can trig the first sensor wait for it to receive and then trig the next sensor wait for it to receive and then trig the last sensor and wait for it to receive without a for loop?
Yes, you either have to wait a while, or place those sensors far away from each other so they don´t collide. I believe you can set the timeout time for each sensor, otherwise, it might take up to a second to wait for a reflected signal.
Wow, this is some next level sht! Awesome work, great video with lots of information and basically a step-by-step tutorial for it. I did not understand half of it, even though I made myself an Arduino uno oil temp and pressure (and battery voltage value with voltage divider resistors) gauge for my car.
@@upir_upir I am glad you are interested in my project. I will try to make a video about it, how it works, codes, and sources (if I can find them). I also made a 3D printed plastic case for the Arduino and the screen with XHP connectors, and an adapter for the sensor. Unfortunately, I was not able to add to my car, cannot find a good place for the sensor without a bigger modification.
Great, I look forward to that video, and I would be happy to promote it on my channel. Please let me know once you have it and good luck with your projects!
@@upir_upir I just uploaded the video about the oil pressure and temp sensor with OLED display :) Here you can check it out. th-cam.com/video/Wn5kIrU5_tc/w-d-xo.html
@@Mr.Bearded.Mechanic This is great, thank you for posting it! It´s a shame it wasn´t installed in your car, I would love to see it in action. Does that sensor reports both the temperature and pressure?
In a beginner to this and don´t know programming, but i tried this as a little school project for my soon to be future older car. I have a question. Would it work to somehow install a small buzzer och speaker to play a sound as the objects come closer? When I ran the program I saw a little speaker icon on the display, is this already a feature? And then what pins is for the buzzer? Thanks for any help!
Yes, the buzzer could be easily added. Right now, it´s not supported in the code. If you google wokwi buzzer, you can get a lot of different examples. This is a one line of code that will play a tone on a buzzer connected to pin 8: tone(8, 262, 250); // Plays 262Hz tone for 0.250 seconds Good luck with your project!
Díky za komentář, do budoucna to určitě plánuji, ale teď bohužel nemám kapacitu natáčet dvě verze videa - hlavně teda proto, že nestačí jenom namluvit českou verzi, když všechno ostatní (proměnné, komentáře atd), jsou stejně v angličtině...
because of exporting the "sensors..." layers as rectangles, my screen is showing them as rectangles and they are overlapping with each other. Is there anyway to overcome this?
I am having an issue with the sensor images overlapping on the display. For example the sensor 1 B black background is on top of the sensor 1 C white section. Anyone know where I went wrong? I have retried the background fill with “black” and “color burn” multiple times but keep getting the same result.
This fixed it! Thank you! If others are reading this, I should have mentioned I am using the library U8g2lib. I could not get Ug8 to work with the teensy 4.0 and ssd1309 screen I have but I was able to get U8g2 to work.
Hello! The project is amazing! I am trying to do something similar but on a ILI9341 2.8” display with a resolution of 320X240 pixels and I cannot upload the image to the display. Can you guide me in this manner please?
Thank you, I’m glad you like it! Unfortunately I don’t have any experience with that screen, but it’s on my list of the displays to try. Once I do that, I will surely record a video. I’m sorry I cannot help more right now.
I implemented this method in a project, but unfortunately, it is not suitable for production because the lag caused by the constant updates of the image is too significant for the Arduino processor.
You can try to use a different Arduino or Arduino compatible board. I have an older video where I was testing a board that was fully compatible but 5x faster.
I think it's pronounced "say-lee" (but I am NOT an authority on it!). Man, I'd _love_ to see what you and Posy could come up with if you designed a display together! I recommend his video on 7-segment displays if you haven't seen it already :) th-cam.com/video/RTB5XhjbgZA/w-d-xo.html
Thank you for the clarification. I have indeed seen the 7-segment video multiple times, it´s a masterpiece! Who knows, perhaps there will be some cooperation in the future..

Thank you for your comment, I actually hope that most viewers would prefer the 1x speed as this is the speed I talk.. good luck with your projects!
I hope you can create it with a buzzer. It can raise awareness for drivers when backing up.
Yep, that should be simple. I just hate hearing the buzzer sounds :)
What an amazing video, you cover so much detail. I be watching this many times. Your knowledge is astonishing. 👍

Great project! I think a buzzer would be a great addition.
Thank you. Yes, I agree. I might add the buzzer and record additional quick video in the future..
Great job, only 99% of parking systems use four sensors, not three sensors.
Thank you; it should be simple to expand the sketch with as many sensor as you like. I only used 3 because the display was tiny to show more info.
