Interfacing Seven Segment Display with AVR Breakout Revision as of 10:49, 4 April 2016 by Nitish (Talk | contribs) (diff) ← Older revision | Latest revision (diff) | Newer revision → (diff)

After blinking the LED , Let's display user information like numeric value using seven segment display. In this tutorial we will interface a seven segment display to AVR breakout board and display a single digit hex (0-F).

Basics

For this tutorial we are using common anode seven segment display. To drive this display we require a BC 547 transistor. The PORT B is connected to data lines of the display and PORT D0 is connacted to base of the transistor as shown in hook up.
