Learn how to hook up and drive a 7-segment LED display using the Arduino. We will use the Arduino alone to display numbers and letters (a-f) on our LED display.
Using the Arduino development platform you will learn how to display numbers and letters on a single 7-segment LED display. There are many ways to drive 7-segment displays, and this is a fairly simple method. However, using this method to drive even one LED 7-segment array "burns" (occupies) many of the digital I/O pins on your Arduino. In later projects, I’ll show you how to use a dedicated 7-segment LED driver.Related
