This useful lecture handout (from a Stanford electronics course) comes courtesy the always insightful johngineer. While something inside me died when I read that aesthetics “is a foreign term to EE’s anyway”, it’s a great summary of some of the issues that need to be kept in mind choosing the right capacitor for the right situation, and describes some common situations where you’d use a capacitor and helps you select the right tool for the job. Read Capacitors Demystified for more.
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
