Very thin copper—called “Electro-Sheet”—is bonded to a plastic laminate panel. On this copper sheet you print the wiring circuit you want with an ink that resists acid. Then you etch away the unwanted metal, leaving the pattern intact. This type of circuit is far superior to wires. It is accurate, compact and stable. Next you snap-fasten tube sockets and other parts in place and dip-solder the connections. To make a hundred electrical connections this way takes only a few seconds.
With printed wiring and other devices—such as transistors—electronic experts are concocting match-box-size hearing aids, vest pocket radios, more compact TV sets and portable electronic “brains.” They are speeding up the production of precision instruments vital in the operation of aircraft and control of guided missiles.
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.
