Here be gators! Rawr! We’ve added a set of alligator clips to our Fritzing collection on GitHub (in the “AdaGators.fzbz” file). For true-to-life diagrams, the six colors and the clip size match our #1008 Small Alligator Lead Test Clips (and also used in some of our Flora and Gemma starter packs).
Please note that these are not “functional” in Fritzing — they don’t make electrical connections between parts they contact — and are merely visual doohickeys to spice up illustrations for better project documentation. (Draw wires directly between parts if you need a viable schematic.)
