Now we will go further and will interface more complex peripherals. In this tutorial we will interface common anode 7 segment display to the starter AVR board. To get idea about basics of 7 segment display check out our Interfacing Seven Segment Displays with AVR tutorial.

Basic

In this example we are using common anode type of 7 segment display. To give positive voltage to the common anode I am using BC547, N-Type transistor as a driver and PD0 is used to drive this driver. Data lines of display is connected to PORTB. Do the connection as shown in hookup and flash the code.
