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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
