This tutorial will take you through the basic elements of circuit design, with the goal of preparing you to design and build robotic sensors and control systems. The experience of designing and building is at least as important as gaining conceptual understanding.
An oscilloscope is an invaluable tool for learning circuit design — it provides a way of seeing what is actually happening to your signals and waveforms. Unfortuantely, oscilloscopes are somewhat expensive. If you don’t have access to a ‘scope, it is possible to use the data-logging features of the Lego RCX in its place
Op-Amps are the first components we’ve used that are integrated circuits, which are also called IC’s or chips. IC’s are easy to use, but we need to know a few things about them.
D. Sculley, Ph.D. an Alum of Tufts University wrote this tutorial in the summer of 2004, teaches basics of electronics, created for Tufts Robotics.
