no notes and dont change ( (PB0) (PC2) (PD5) (PA0)(PA1) (PA2) )

You have an AVR ATmega16 microcontroller, a red LED (PBO), a green LED (PC2), a yellow LED (PD5). and three pushbuttons switches. When S1 (PAO) is pressed, the three LEDs will blink at the same time on and off six times with one second total delay time for every blink. When S2 (PA1) is pressed, the three LEDs will blink in sequence with a 250 ms total delay time for every blink. When S3 (PA2) is pressed, the three LEDS will light and stay like this. [50 points]
