MOORE’S LAW—the prediction made in 1965 by Gordon Moore, that the number of transistors on a chip of given size would double every two years—has had a good innings. The first integrated circuit (invented by Jack Kilby of Texas Instruments, see above) was a clunky affair. Now the size of transistors is measured in billionths of a metre. Moore’s law has yielded fast, smart computers, with pretty graphics and worldwide connections. It has thereby ushered in an age of information technology unimaginable when Dr Moore coined it. Not bad going for what was originally just an off-the-cuff observation.
That observation, however, is not truly a law. It is, rather, the description of a journey of many steps, each a specific technological change (see chart below). That new steps will happen is as much an article of faith as a prediction. Every time transistors shrink, they get closer to the point where they can shrink no further—for if the law continues on its merry way, transistors will be the size of individual silicon atoms within two decades.
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.
