SIK Projects

Measuring internal resistance

One common complaint with the SparkFun Inventor’s Kit (SIK) is that there are no directions for taking it past the simple “experiments.” The guide is not particularly project-focused, so I was asked to make some tutorials that showcased projects made from the SIK.

I did my best to use only parts found in the SIK, but a few required some extra pieces. Since these are relatively simple projects, I listed them all here.
