Write a C program using AVR studio

Write a C program using the two Templets (internal interrupt & External interrupt) Setup the Arduino Uno-R3 by connecting six LEDs to pins PD0-PD5 and one Ultrasonic Sensor to PB0 (PCINT0). Moreover, you will write two C programs (one uses timer (internal) interrupt and the other uses internal and external interrupts). You cannot use any delay function for this assignment except to trigger the Ultrasonic Sensor (see template C file). Make sure you use the “volatile” keyboard properly. 1) Write a C program to setup Timer1 interrupt (this in an internal interrupt.) The Interrupt Service Routine (ISR) keeps track of timing using volatile global variables. To help you write the entire program, you can use the template provided. The LED connected to PD0 will go through the following sequence: After exactly, 10 seconds, the LED should turn ON continuously for 6 seconds and then turn OFF for 10 seconds. This should repeat indefinitely, i.e., ON 6 seconds, OFF 10 seconds, ON 6 seconds, OFF 10 seconds, etc. Use the template code provided on Blackboard. Note: make sure you use at least 330 Ohm resistors in series with each LED as shown in the figure below. 2) Write a C program to handle external interrupts (PCINT0) in coordination with timer0 and timer2, where the Ultrasonic Sensor connected to PB0 responds with a pulse. Your code should calculate distance from sensor and display it using the LEDs. The Ultrasonic Sensor HC-SR04 measures anywhere between 2cm and 400cm. The sensor responds with a pulse whose width is related to the distance by the formula: distance in cm = time in microseconds / 58. a) Distance measure (DM) < 10cm, LEDs ON represent number 1 in binary (0b00000001) b) 10cm <= DM < 20cm, LEDs ON represent number 2 in binary (0b00000010) c) 20 <= DM < 30cm, LEDs ON represent number 3 in binary (0b00000011) d) Similarly, for every 10cm increment, the LEDs turn on proportionally as in parts “a”, “b” and “c”. The final value390cm <= DM < 400cm, LEDs ON represent number 40 in binary (0b101000). To ensure proper blinking rate, use the oscilloscope.
