I hand these cards out at convention panels & workshops along with a couple LEDs and a coin cell all in a 3×4″ Ziplock-style bag. There’s three double-sided cards: one for electronics principles, one for Arduino, and one with some terminology and eye-catching photos. Though designed for beginners, I’ve had a few pros ask for spares too! (The resistor color codes seem especially popular.)
Adobe Illustrator format. These are sized for Overnight Prints‘ standard business card template; full color, double-sided…rounded corners are optional but add a touch of class (and won’t cut off any information). Creative Commons license, feel free to print your own, remix and share!

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.
