Have you noticed how the blinking LED of the MacBooks causes a soothing, kind of hypnotic effect? No wonder why…
Apparently, the behavior of the LED while the computer is sleeping is tuned to resemble the human breathing rhythm at rest! Things like these give a better understanding of Apple’s meticulous attention to detail and how much of your MacBook’s $999 went into patent attorne– ALL GLORY TO THE BREATHING LED!
The breathing effect is a natural step forward from the dull and classic “hello world” blinking LED. If you want to add it to your project, you need a spare Timer and a few lines of code. Here is how…
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.
