Breadboard: Push Button and Two LEDs connected to Microcontroller with Hardware Debouncing

Breadboard circuit of one button with hardware debouncing and two LEDs (Light Emitting Diodes) connected to an AVR microcontroller. The push button switch is connected to pin 1 on PORT B and the LEDs are connected to pin 0 and pin 2 on the same port. These are green LEDs so a 330ohm resistor is used to limit the current through the LED.
