The team from the University of Exeter believed that the green light emitting diodes (LEDs) can help sea turtles spot the mesh netting and avoid it without disturbing the fish. They tested their prototype off the Peru coast in a controlled experiment.
The fishing nets not fitted with LEDs had 125 green turtles caught in the netting while the lit one only had 62. The numbers of guitarfish caught by the two nets were not affected by the illuminating add-ons.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
