LEGO BOOST Radio
All we hear is...
Today we are used to digital radio equipment that search the stations automatically, and tune themselves on the right frequency on their own. But old analog radio receivers had to be tuned by hand. This LEGO BOOST old-fashioned radio works like an old vacuum tube analog radio: one knob allows you to "tune" on different stations, and change music, anothe knob lets you tweak the volume. But make sure to position the antenna correctly, or the music will come out distorted. Like in the old radios, a light (the "magic eye") will turn green when the tuning is correct.
