I think that question is asked earlier. Check the comments. The short answer is: I can’t guarantee it, and it will not be able to handle as high baud rates.

This is straight forward, but you need to open Arduino Ide Two times. You can also open a different serial terminal program. Like this which is browser based: www.serialterminal.com/

Hello, Thank you. Can you tell more about this?

would you be able to look at the Info on my Page?

Thank you! I have updated the video description with the modbus Libraries. Also check out my previous video where I am using modbus for data logging.

Thanks for letting me know about the other videos. I should thought about that. I appreciate you sharing all of this. I will be watching for more. Like I said, I am relatively new to Modbus and this is my first exposure to Ignition. Your videos will definitely help me in my journey. Thanks again and I am looking forward to more.

Thank you! Yes, i chose it because it was the simplest option (that I knew). I could have exposed ignition directly as you said, but that would require port forwarding and knowledge of my router IP address. It is generally the simplest to push data to the cloud.

Another option might be to use the ignition gateway-network, and connect my ignition gateway to an ignition gateway sitting in the cloud, and use that for accessing the gui. But I haven’t checked if that’s the correct way of doing it.

Yes, i think so! I’m just hopping the plastic doesn’t loose too much stiffness over time.

"enable your anxiety" yea what the fuck are you on about

Naaaah💀💀💀

It might be that the photoresistors are too slow. Can you try photodiodes? Can you set the Arduino pins to normal digital input and digital output and see if the signal is received correctly?

Can I please get an email adress so I can send you and ask you about the issues I'm facing, if you don't mind? I am an Engineering Physics student in my last year in Turkey, and I'm doing this project as a part of my senior project@@BV-labs

@@nedaa8829I can try to help here.

@@BV-labs .

​@@nedaa8829same bro, I am here with the same project, 3rd yr btech in electronic and communication, can u help me I tried with phototransistors, it doesn't work

I think you are right

Not sure

Wintergatan's holy grail

I think they have a lot in common since they reduce the pressure by leading it into the wall!

Can you be more specific? Are you trying to install the software or hook up the circuit?

I am trying to control some industrial devices using raspberry pi

Thanks, The square-axle part of the friction pin is actually put into a round hole on the rotor, so there is not a lot of friction there

@@BV-labs oh didnt see, nice!

The Arduino’s do not need any synchronization. The light beam works exactly like an electric wire. It transmits a true/false signal. The uart protocol takes care of the signal, exactly like it does on a wired connection.

@@BV-labs Brother can get the code details!

@@chintavishnuvardhan8379 hi, all the necessary code is visible in the video

​@@BV-labsHey why did you use pin 13 there is no connection regarding that pin in the code " line 6 "

wpa_supplicant isn’t installed by default on Debian, but you can install it with this command: «sudo apt install wpasupplicant». Then you should be able to follow the video.

Thank you!

Thanks

Thank you!

I tested this just before the video was published, so i would guess it still works

You can see the complete code at 0:40 in the video

@@BV-labs thx and can I use ldr sensor and laser module as tx and rx

yes, it should be possible, but it might not be able to handle a high baud rate. A photodiode is probably faster on the receiver side. Also, make sure the laser does not draw more current than the Arduino can handle.

Thank you!

You can see the complete code at 0:40 in the video

Is The code same for both transmitter and receiver arduino ! If you don't mind please share the schematic of the circuit it will be help ful to avoid mistakes ❤​@@BV-labs

@@chintavishnuvardhan8379 Yes, the sender and receiver work exactly the same. Both sides are actually both senders and receivers. They use the same code and the same Circuit. I dont have any more drawings of the circuit than what you see in the video.

​@@BV-labs Thanks For Helping One last help can I use ldr instead of Photodiode

@@chintavishnuvardhan8379 it might be possible to use LDR, but you might have to adjust the resistor value. Also, it is a bit slower, but I guess that doesn’t matter at 9600 baud. Another thing you could try is to use a normal led the same way as a photoresistor. It should in theory work, but I haven’t tried.

Thanks! I can check tomorrow. I think the most important parameter is that the two diodes are made for the same light wavelength. Theoretically it should be possible to use the same device in both ends, but i did not try that. What are you planning to use it for?

@@BV-labs I'm hoping to use it for underwater communication.

Thanks for checking!

@@vanmunch36 Interesting!

The photodiode i used was "ams OSRAM, SFH 229 Full Spectrum Si Photodiode". I don't have any data for the LED.

Hi, it was designed in Autodesk Fusion 360

@@BV-labs is it free or paid

@@ShortMovieS365 They have a version for hobbyists. Search for Fusion 360 for personal use

Thanks!

Thanks! Very satisfying when it works! It doesn’t go viral anytime soon 😜

Good idea! Just a gearbox and some wheels and it should be good to go!

@@BV-labs I wish you best of luck! :)
