## Description

USE PYTHON 3 ONLY

1. The voltage is 3.3V across the circuit. Determine the resistance of the resistor based upon the color of the bands. Based upon the voltage required by the LED, compute the current. Please refer to the PowerPoint presentation to determine how much voltage is required by the LED.

2. The voltage is 3.3V across the circuit. Determine the resistance of the resistor based upon the color of the bands. Based upon the voltage required by the LED, compute the current. Please refer to the PowerPoint presentation to determine how much voltage is required by the Infrared LED.
3. Declare a list that is initialized with six of your favorite sports teams. Print out the number of teams to the shell. Use a for loop to print out the teams to the shell.
4. a. Declare a list, initially with no elements.
b. Use a while loop to prompt the user for a sporting goods item and append the item to the list.
c. Break out of the loop when the user enters exit; do NOT append the word exit to the list.
d. Write a for s in sport_list loop to print out the elements in the list to the shell.
(BONUS) Add code to handle a ctrl-c exit.
5. a. Create a list which initially contains no elements. b. Using the SenseHat, take 25 pressure measurements and store each measurement as a floating point number in the list. Be sure to have the program sleep for a second or two between each measurement.
c. After recording the measurements, calculate the average of the pressure measurements- use the sum function and display the average on the SenseHat.
6. a. Create a list of lists consisting of three rows and four columns and have the user initialize each element in the list of lists.
b. Compute the sum of all of the elements in the list. You may use the sum function.
c. Prompt the user to enter a row number and use a loop to calculate the sum of the elements in the row and print out the sum.
7. a. Create a new file (module) named camera_picture.py.
b. Write a function, take_picture, that takes two parameters, the filename and an effect.
c. Take a picture with the filename and effect.
d. Create a second file use_camera.py.
e. Import the take_picture function from the camera_picture module.
f. Prompt the user for the filename.
g. Prompt the user for the effect.
h. Call the function with the filename and the effect as arguments.
(BONUS) Print a menu that allows the user to select an effect with a letter. Call the function with the appropriate arguments.
a. cartoon
b. pastel
c. emboss
etc.
(BONUS) Write a function that lights up one row of the SenseHat LED display at a time and does so indefinitely. Have the program sleep for a second or two each iteration through the loop. Also, the row of lit LEDs should be set to a different randomly create color each iteration. The user can break out of the program by pressing ctrl-c. Wrap the function in a
try-except block to handle the exit gracefully.
(BONUS)
a. Create a new file (module) named light_sound.py.
b. Write a function, alert_fun that takes one parameter, the GPIO pin for the LED, the GPIO pin for the Buzzer, and the duration of the light to be on and the buzzer to sound.
c. Create a second file use_light_sound.py.
d. Import the alert_fun function from the light_sound module.
e. Prompt the user for the GPIO pin for the LED, the GPIO pin for the Buzzer, and the duration.
d. Call the function with the duration as an argument.
