These stickers are a must for anyone making a breadboarded Arduino-compatible.
They fit right on top of a DIP ATmega328 (or '168) chip, and clearly indicate every pin as it would be called in the Arduino IDE. No more looking up the datasheet or schematic! The stickers are made of a tough vinyl, usually used for bumper stickers, so they will not fade, scratch, or wrinkle. The stickers are die cut already into a rounded rectangle that fits on top of the AVR
Comes in a pack of ten, so you never need to feel like you're about to run out. AVR chips are not included
