Each month this year, we’re exploring a different electronic component, delving into what it is, how it works, and how you use it in projects. Last monthwe looked at batteries. This month, we’ll tackle the resistor, the job of which is to limit the flow of electricity and thereby control it, guiding it toward one component while protecting another. As always, we’ll start things off with an introduction to resistors via an edited excerpt from Charles Platt’s essential Encyclopedia of Electronic Components: Volume 1.
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.
