FM radio broadcasting was invented in the United States in 1933. After a slow start, it became wildly popular all around the world, largely because the frequency modulation technology used offered better sound quality than the existing amplitude modulation (AM) transmissions.
But the era of FM radio may be coming to an end. After more than 60 years of using the system, Norway is set to become the first country in the world to turn off its FM radio network — and others may soon be following its example.
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.
