Arduino Optical Fiber Data Transmission
In my setup for Arduino optical fiber data transmission, I’ve chosen to employ the Amplitude Shift Keying (ASK) scheme. This communication method allows two Arduinos to exchange information through an optical link. To make this work, I’m relying on the Radiohead Amplitude Shift Keying Library. This library serves as a handy tool, simplifying the implementation of ASK in my project, making the communication process between the Arduinos efficient and effective.

Transmission Setup:
Build the transmitter and receiver circuits according to their diagrams and connect them to their respective devices. The transmitter circuit includes the following components:
– Microcontroller (Arduino)
– HFBR-1414 Optical Fiber Cable Transmitter
– SN75452B Switching Driver
– Resistors with values of 10K (1) and 56 ohms (1)
– Capacitors with values of 0.1uF (3) and 10uF (1)
Here are the circuit connections on the breadboard.
Here is the full setup with Arduino Transmitter and Receiver Circuits. Connect the fiber cable and power up the boards.

Arduino Optical Fiber : Bidirectional Communication
Here is an Arduino Optical Fiber bidirectional communication example:
This demo shows how Arduino can send data through light cables. Two Arduinos talk to each other using UART, controlling a moving part and light intensity. I tested it and it worked well over a distance of 342 meters. I made some adjustments to the sending part, and everything still worked fine. You can get all the things you need, like the code and the models for sending and receiving, from this post. If you want to understand it better, there’s a video you can watch too. It’s like a simple chat between Arduinos using light!
