Homework 4: Traffic Lights Control Using Sequencers This homework is to develop a 2-way traffic lights control solution by using sequencers in LogixPro simulation. Recall what you have done in Lab 5 where you used six TON timers to control two-way traffic lights. This homework is very similar to what you were asked to do in Lab 5, but this time you need to use Sequencers (SQO instructions) and a single timer instruction to do it (see the example in my video clip). Red = 0:2/00 Amber = 0:2/01 R. Green = 0:2/02 Red = 0:2/04 Green = 0:2/06 Amber = 0:2/05 8 sec. 4 sec. 1s 8 sec. 4 sec. In addition, you are asked to control the pedestrian crossing light on and off together with the traffic lights according to the rights of road. Also, when either direction of the traffic lights turns to Amber, you need to blink the Walk light at 0.1 seconds interval to warn pedestrians until the Amber light went off. No subroutines are needed for this homework. Try to think about a way of using the 0 bit of the ACC value of the timer to blink the pedestrian crossing light.

What is the digital revolution and how did it change society? what are the benefits of digital media?

Write a program that displays the following menu: geometry calculator 1. calculate the area of a circle 2. calculate the area of a rectangle 3. calculate the area of a triangle 4. quit enter your choice (1-4): if the user enters 1, the program should ask for the radius of the circle and then display its area. use the following formula: area = ď€(the square of r) use 3.14159 for ď€ and the radius of the circle for r. if the user enters 2, the program should ask for the length and width of the rectangle and then display the rectangle’s area. use the following formula: area = length * width if the user enters 3, the program should ask for the length of the triangle’s base and its height, and then display its area. use the following formula: area = base * height * .5 if the user enters 4, the program should end. input validation: display an error message if the user enters a number outside the range of 1 through 4 when selecting an item from the menu. do not accept negative values for the circle’s radius, the rectangle’s length or width, or the triangle’s base or height. note: if the user enters an improper menu choice (1-4), the program prints "the valid choices are 1 through 4. run the program again and select one of those." if the user enters a negative radius, the program prints "the radius can not be less than zero." if the user enters a negative value for height or base, the program prints "only enter positive values for base and height."
