thank you. I had problems as I didn't know what is serial begin. and you told us if this doesn't match with serial monitor you cant see anything thank you!
You are welcome. you might then be interested in my course published on Udemy, but I am now sharing it on RUclips. Starts here for free robojax.com/L/?id=338
Hello, great tutorial and very practical, my question is how to change the code to invert the bar graph indication, I mean that the maximum approach of the object to the laser sensor would cause the bar graph to increase and moving away from it would cause the bar graph to decrease, in advance Thank you and best regards
Could you cover the programming of Arduino in detail? I am looking for a series which is targeted towards intermediate to advanced. Would def support you on that.
@@robojax They are dirt cheap. I tried to see how much you charged, but I could not find an add to cart. Nevertheless, I usually only buy the 8 pin dip.
on my arduino uno(s) the SDA & SCL connections don't work, only A4 & A5 (also with scanner I2C), so I get on the screen Dist.: -1mm and that's it. Have a lay-out picture of an Arduino UNO that even have these connections on board; it is possible to use A4&A5 for both VL53l0X and 1602A? adresses are resp. 0x29 and 0x27, thanks
@@robojax soldered the wires together and now it works just like you showed in your video It is now easy to make a condition, when the distance is equal or below a certain value(someone passing, or an obstacle) a led is blinking or something else. thanks again Robojax!
Yes there are but it will be $1000 or higher. you may get regulator laser distance sensor and modify it for your purpose like this www.amazon.com/dp/B07YHTD5M5
you need to watch two videos before coming to this video. 1-Watch introduction to LCD so you can print simple text on screen ruclips.net/video/pxUjEsJQW2M/видео.html 2-Watch introduction to VL53L0X so you can measure the distance and dispaly it on the serial monitor ruclips.net/video/CUg8VheNyoU/видео.html then come the bargraph and it will work.
Hi, they have not mention it , if you means minimum distance, no it won’t. But if you are referring to 1mm resolution, it depends on reflectivity of the surface. See datasheet.
Hello it means you did not watch the video and skipped it. This video requires 2 other videos to be watch and instructions followed. Apparently you did not follow them.
sorry, it means you have to install the library. please watch this video ruclips.net/video/q9YC_GVHy5A/видео.html it has subtitle in almost any language.
Watch the main video on VL53L0X and I have explained it there. I have a link for that in the description where you can get the code and see this video.
thank you again, I was waiting for this video and it came very soon; very good explained and usefull for many projects!
You are welcome. I am glad you found it useful.

I have Arduino course that starts from beginners and up. bit.ly/rj-udemy I am still adding contents to it.
Great video as always. Have you tried running it on an ATTiny 85 yet or does it take up to much memory? It does have more than enough pins.
If I got a chance, I will have to test it.
@@robojax They are dirt cheap. I tried to see how much you charged, but I could not find an add to cart. Nevertheless, I usually only buy the 8 pin dip.
did you manage to get it to work?
How could I use the LCD and the TOF in the same time using arduino uno? which only had A4 and A5 for scl and sda? thank you so much in advance.
use breadboard and connect them together. you may look at this video ruclips.net/video/L6ekl2ABcuY/видео.html

Yes. I did not want to use breadboard. You can connect up to 128 devices.
@@robojax will try that, thank you

You are welcome. Pleased to hear that. Have fun.
Should be able with LASER to do Real Numbers i.e. fraction of a millimeter e.g 5.05... 5.06 .... 5.07 etc...
it is all real number in millimeter. I changed to cm
@@robojax Hi sir, how do you change it to cm?
Do there any sensors meagrue distance for many meters
For example 300 meters
Yes there are but it will be $1000 or higher. you may get regulator laser distance sensor and modify it for your purpose like this www.amazon.com/dp/B07YHTD5M5
Can it be used for water tank level detection
I have not tested it. No sure. I will make a video for water level detection.
No matching function for call to 'LiquidCrystal_I2c ::begain() '
of course if you skip the video and don't watch, this is what happens.
you need to watch two videos before coming to this video.
1-Watch introduction to LCD so you can print simple text on screen ruclips.net/video/pxUjEsJQW2M/видео.html
2-Watch introduction to VL53L0X so you can measure the distance and dispaly it on the serial monitor ruclips.net/video/CUg8VheNyoU/видео.html
then come the bargraph and it will work.
Where is LcdBarGraphRobojax.h library available?
what the first 30 second of the video, I have mentioned it.
👌👌👌
Thank you. Sorry I missed your comment. RUclips now allows me to see comments I have not replied to.
Hi there, will a TOF sensor read down to 1mm?
Hi, they have not mention it , if you means minimum distance, no it won’t. But if you are referring to 1mm resolution, it depends on reflectivity of the surface. See datasheet.
hello can you help me with this error( lcd.begin();) (no matching function for call to 'LiquidCrystal_I2C::begin()'
)
Hello it means you did not watch the video and skipped it. This video requires 2 other videos to be watch and instructions followed. Apparently you did not follow them.
@@robojax I watched the video 3 times but my English is very bad. Thanks for the help, I'll watch the rest of the videos.

@@robojax thanks
How much distance can be measured with this sensor
Watch the main video on VL53L0X and I have explained it there. I have a link for that in the description where you can get the code and see this video.
@@robojax ok thanks
You are welcome.
