Q5: Write a program using Arduino to control LED (One or more ON/OFF) or Blinking.

Note: Multiple "View Code" buttons may indicate different solutions to the same question or sub-parts of the question.

Q6: Create a program that illuminates the green LED if the counter is less than 100, illuminates the yellow LED otherwise.

Q7: Create a program so that when the user enters 'b', the green light blinks, 'g' the green light is illuminated, 'y' the yellow light is illuminated, and 'r' the red light is illuminated.

Q8: Write a program that asks the user for a number and outputs the number squared.

Q9: Write a program to control the color of the LED by turning 3 different potentiometers. One will be read for the value of Red, one for the value of Green, and one for the value of Blue.

Q10: Write a program to read the temperature sensor and send the values to the serial monitor on the computer.

Q11: Write a program so it displays the temperature in Fahrenheit as well as the maximum and minimum temperatures it has seen.

Note: Multiple "View Code" buttons may indicate different solutions to the same question or sub-parts of the question.

Q12: Write a program to show the temperature and display a graph of the recent measurements.

Q13: Write a program using a piezo element and use it to play a tune after someone knocks.

Q14: Understanding the connectivity of Raspberry-Pi /Beagle board circuit / Arduino with IR sensor. Write an application to detect an obstacle and notify the user using LEDs.
