the AFMotor library installed, launch the Arduino IDE. Let's write a sketch that will test the stepper motor. The code will do the following: 1. Load the AFMotor library. 2. Create an AFMotor stepper motor object and set the stepper's connection and steps per revolution (i.e., how fast the stepper motor's shaft rotates). 3. Move the shaft clockwise and counterclockwise using the stepper motor's two coils. By the way, this action is known as double-coil activation, and it produces greater torque compared to using just a single coil at a time. We will need that extra torque to move the curtain string.

use Pyhton. The tossball simulation we developed together in class is attached to this week's notes. Study it carefully to understand exactly what it is doing. It currently launches a ball in the main graphics window. You need to make the following changes and improvements and send me at the end your finished project in zipped folder format. Only python modules should be included. 1) Add a new class named "Cannon". This class it to represent the cannon that launches the balls. It should draw a rectangle (hint: use Polygon class from Graphics.py) at the launch point. Its width should be equal to the diameter of the balls that it shoots out and its length should be proportional to the speed, say something like speed * 0.15. The cannon should also be directed in the same direction that the balls shooting. Add proper width, height, and angle attributes to the class for supporting the settings above. The balls should start from the bottom of the cannon and be projected out through the…

Implement the following in the .NET Console App. Write the Bus class. A Bus has a length, a color, and a number of wheels. a. Implement data fields using auto-implemented Properies b. Include 3 constructors: default, the one that receives the Bus length, color and a number of wheels as input (utilize the Properties) and the Constructor that takes the Bus number (an integer) as input.
Write a method that takes two string parameters, and tells whether the first is a substring of the second. You can't use framework methods that do this for you, such as indexOf(). In other words, you have to write the loops yourself. But, you can use the primitive methods such as charAt(). Also analyze the program's performance and state the big-O complexity of your method. Provide a screenshot of the code working.
