For example, the upper tube can be drawn with: # An array of coordinates for the tube A more efficient approach is to define an array of ( x, y) coordinates and move to each position in the array. Simple turtle commands like move, left, right, and forward are great for drawing simple graphics, but they can be awkward if you want to create a more complex drawing. The Python Turtle example in Listing 1 shows three basic concepts I use in this project: drawing lines, moving without drawing, and adding text ( Figure 1). A new turtle is placed at the center of the screen, position (0,0), facing right. To create a turtle object, you use the myturtle = Turtle() statement. Turtle objects have properties for color and line thickness and a number of additional methods for shapes, fill, circles, and text. If you want to move a turtle without drawing a line, you use the penup() method then, once you arrive at the desired location, the pendown() method lets you start drawing again. With the use of methods (e.g., forward(), backward(), left(), and right()), you can draw lines. The turtle library is used a little bit as you would use a pen on a drawing board. The Python turtle library is probably already loaded on your Raspberry Pi system, but if it is not, enter: pip install turtles In this article, I share a Rasp Pi Turtle project that creates a graphic of an "old style" mercury thermometer animated with a Pi temperature sensor. I found that once my kids understood Turtle basics, we were able to do more advanced Raspberry Pi projects that used sensors, push buttons, and outputs. The Python turtle library offers simple step-by-step graphical methods that allow young programmers to create graphics with only a few lines of code. However, if you are already an expert in this field, this will be a very limited tool for you as it doesn't allow you to go very far and do more progressive programming activities.Turtle graphics are a great way to get kids started programming. It is highly intuitive mainly because of its simple user interface that allows you to explore and perform tasks in no time. MSWLogo is a great way for beginners and kids to get started in Logo-based programming. Most importantly, you no longer need further setting configuration to make this run. This PC programming environment can easily be installed in your system as quickly as possible. Moreover, it provides support for multiple turtles and 3D computer graphics. There are non-English kits available for this desktop app also such as German, Portuguese, Japanese, and two French adaptations. Thus, if you own a modern system, it is more recommended for you to download FMSLogo instead. It is important to note that this software solution is mostly compatible with older versions of Windows. You will be able to officially download this programming tool on its developer page. How can I download MSWLogo on my computer? On the other hand, there are also tons of tutorials and even video guides to get you started with Logo thus, you'll be able to build your own square or graph in no time. Its operation is a bit like using MS Basic itself so if you are familiar with it, you won't be required of any learning curve. It is remarkably easy to learn but not in any way a boring platform as it contains graphs and charts that you utilize interactively.įurthermore, its user interface is just as basic as it gets. It is a convenient option to learn to program especially for kids or beginners in programming. MSWLogo is ideal to be used in creating games or software dedicated to Windows.
