Makers, developers and Arduino enthusiasts may be interested in a range of electronic and Arduino reference cards that are available from Github and can be printed off for reference at any time.
The reference cards have been created to provide three double sided cards with one for electronics principles, one for Arduino, and one with some terminology and images and have been designed for both beginners and those that needed quick reference.
Business card-sized references for Arduino and basic electronics. I hand these out at workshops along with a couple LEDs and a coin cell all in a 3×4″ Ziplock-style bag.
These are NOT exhaustive references, this is by design. 80/20 principle applies…the most common and essential information in the least space. They’re designed for beginners and the goal wasn’t really to answer all questions, but to plant seeds: “Oh yeah, those resistor stripes mean something” or “Oh yeah, more current needs bigger wire” — serious study then takes place elsewhere. Case in point, 5-band resistors aren’t even mentioned, too esoteric at this early stage of learning. The reverse of each card is flipped on purpose. Placed on a desk, it’s easier to turn the cards over vertically.
Adobe Illustrator format. These are sized for Overnight Prints’ standard business card template. While not the absolute finest quality, they do okay and provide good value…getting these in the most hands possible was the goal. Rounded corners (optional) add a touch of class and won’t cut off anything vital. Overnight Prints’ robot WILL complain about the layout (upside-down card backs, etc.) but this can usually be ignored, as long as the preview comps look correct.
