The Arduino Classroom Arduino 101-Chapter 8: Displaying Information

摘要

Last month, we looked at motion and position control using the variable resistance of potentiometers. This culminated with labs that led up to using the turning of a potentiometer knob to control the motion and position of a servomotor. We've learned a lot of fundamental principles for both computing and electronics, and we have reinforced that learning with hands-on laboratory exercises. This month, we will go very light on new fundamental information and have some fun with a bunch of labs that deal with my favorite thing: blinking LEDs. We will look at displaying information using LEDs configured as a bar graph and as a seven-segment single character display.
