To ease myself into this hobby, I began with the SparkFun Beginning Embedded Electronics tutorials. They were a great way to start, and had me well on my way to making my first RS-232-controlled blinkenlight in no time. As part of that tutorial, they told me to install bypass caps near Vcc on all ICs. Okfine, monkey can add prophylactic caps everywhere. But why? The SparkFun page describes their function at a high level, but I've always wanted to know more. Cap monkey want pictures. Cap monkey want to know why he has a pill box compartment dedicated to his supply of 100 or so 0.1uF caps.
This post is what I've been looking for. Details. Pictures. Sample circuits. What more could a cap monkey want?
