Papercrafts at Adafruit! We’re excited to share this Resistor Helper you can download and make yourself. It’s the newest tool in our Circuit Playground family– when you can’t get to your iPhone or iPad, use paper! One side helps you read 4-band types and the other side takes care of 5-band types. The Resistor Helper is on Thingiverse as a PDF (with Illustrator editability preserved). Designed by Adafruit with Matthew Borgatti. You can also grab the PDF on github.
