Use fiber optics to transmit data between arduinos #Arduino
Thanks to Rafa B for sending in this cool Arduino project! Check out the full post here.
Sorry for the watercolor craziness! I saw this pen-tablet laying around so I gave it a try…
The purpose of the Fiber Optic Shield was to allow easy data transfer from subsea scientific instrumentation to the surface (vessel, rig, buoy, shore etc). Regarding underwater equipment we have many advantages using optical fibers, like immunity over noisy industrial environments (rigs, ships), ability to transmit over long distances – deep waters, slim cables and so on. But since most people will not be using optical data transfer for oceanography I must attain this text to the technical aspects of this technology. Since I am not a specialist on the matter, please let me apologize in advance for any wrong information.
I should mention I will scratch only the very top surface on the subject, the bare minimum, so you can understand how the shield was designed and how it works.
System Overview
The idea is quite simple, we desire to transmit a piece of information from one place to another. In this case, from Arduino A (brain #1) to Arduino B (brain #2). The first Arduino will use an optical source, in our case a LED but it could be a laser also, to transmit the information through an optical channel – the optical fiber. Reaching the end of the fiber is an optical sensor or receiver that will translate the light pulses to electrical signaling and relay it to the destination, Arduino B.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
