wow. best instructional video i've seen in a very long time. bravo

Very good video, it is rare that people are describing electronics details like that in arduino videos. I appreciate that :)

si i have question : how to connect SFP modul with arduino?

Subbed

Could u make a video explaining a simple DIY protocol for a simple project like a coupled LED and sensor transmiting info between 2 arduinos, i mean, data structure for serial communication, error check etc

@electronicstree

Creating a DIY protocol for a project like this is quite achievable! We can design a straightforward communication protocol utilizing serial communication, implementing error checking mechanisms to ensure data integrity between the two Arduinos. I'll be sure to incorporate this into the upcoming videos.

can optical communication do 2 way comunication betwen 2 arduino just using single core optical cable ?

@electronicstree

8 ай бұрын

The answer is no, and the reason is that with this limited hardware setup of an optical transmitter, receiver, and Arduino, you can't achieve bidirectional communication. For this purpose, you have to choose BiDi transceivers for your two-way communication with a single optical Fiber cable.

Hey! Fantastic video, I was wondering how/if it would be possible to modify this design to work at 6.2 MBaud?

If you're working with microcontrollers, this transmitter and receiver setup should work fine. To answer your question, you just need to adjust the values of the passive components for the transmitter. For the receiver, if you're looking at speeds above 5Mbaud, you'll want to swap out the HFBR-2412 with another model like the 2416. Check out Broadcom's Applications Support Guide for all the configuration details you need.

@@electronicstree Thank you! I will look into this, do you have sample calculations for how you chose your own passive component values?

Could you provide the schematic for the Receiver circuit? I went on all the Arduino links you provided but I couldn't figure out the connections to the LCD. Apologies if I missed it! I really want to try this circuit out. Thank you!

@electronicstree

I have provided the receiver schematic in parts 4 and 5. All you need to do is connect the TTL data out pin to the Arduino RX pin. As for the usage of the LCD, I assume Arduino users already know how to use it because it's a basic thing.

Is it possible to modify the code so that it transmits texts via the serial monitor using this same circuit?

can i use it as for SPI communication?

@electronicstree

6 ай бұрын

If you want to use the SPI interface, you will have to use the number of optical transmitters/receivers and optical fiber cables accordingly to the SPI lines. This is because it requires more signal lines (wires) than other communication methods. Essentially, you have to convert every electrical signal line to a light signal and then convert these light signals back to electrical signals. Therefore, this approach may not be suitable.

Hi bro How to send 3 sensors at the same time ?? Thank you

If you are using UART communication, you can use three modules. You can use Arduino Mega, which has multiple hardware UARTs, and for Arduino Uno, you can use SoftwareSerial. As for ASK modulation, I'm not sure, but the RadioHead library may not support multiple transmitters and receivers in a single network.

Is it possible to have comunication of both boards with one cable?? 😊

Yes, you can, but it would be simplex communication.

The only problem I see here is the price and availability of TX diode HFBR-1414Z and RX photodiode HFBR-2412Z. Currently, prices for these components are around $50. However, the video is very interesting!

The prices I found range from 7 to 10 dollars for each module, while some sites offer them at 20 to 28 dollars. If you find any, you can use any TTL-compatible modules according to their data sheets.

Building a fiber optic splice tool with Arduino is tough because it needs precise equipment like fusion splicers to accurately join and fuse optical fibers. Arduino isn't well-suited for such a complex job.
