We have four tutorials to try out for the Hour of Code. We recommend starting with Hello Codi!, but any of the four tutorials are accessible for novice coders. They can all be completed within an hour timeframe.
If the code.appinventor server (instead of the main AI server) is used to build THEProject, multiple students can access the same Project if they share the Project Entry code. This server can be used without an eMail log in; it requires a pass code. If the students share the pass code, all can access the Project but NOT AT THE SAME TIME. Do you know what the code server is?
I have been slowly implementing iLogic rules into our drafting department. However, my method for developing these rules consists mostly of finding something very similar that someone else has written and modifying it in very basic ways to fit my needs. If there is an issue with the code (which there usually is), my only option is to tweak one thing at a time with barely educated guesses until I get it to work... or give up. This is rather limiting and very time consuming. What would be the best way for me to learn how to actually write the codes myself (AKA, starting with a blank rule and typing). I understand that the internet is still going to be a valuable tool for ideas and diagnostics, however it would be very helpful to have a good foundation of understanding and some knowledge. Suggestions?
So I'm trying to 3d print some "business cards" with some engraved text as well as a QR code that takes you to my website. I've tried converting to an SVG then to a DXF and importing that with not a ton of success. I have to manually click each box to extrude and that doesn't count ones where a dark bit is next a bunch of white bits which makes it very tedious to walk through the QR code bit by bit to make sure its right.
My question is there a plugin or tool that can do this better? Ive seen some people using svg images in fusion 365 but id really prefer to do this in inventor. Any help or advice would be greatly appreciated!
Mark shows a great tool for QR code above, aside of it, you are seems mentioned 3D printing, Emboss is one of commands which can help, how about Grill command under Plastic panel, it would be more efficiency to handle this kind of cases.
Hi @sutherland.casey! I just found this topic and I have the same issue: I would like to engrave a QR-code into an Inventor part, so that also the QR-code is 3D, and not only a flat image "glued" on top of my surface.
@mcgyvr Thanks for your quick reply! Actually, I also found that website and I generated a .stl file of my code, but the problem is that Inventor does not recognize the imported .stl as a closed volume body, so I cannot properly integrate it in my design.
I'm trying to select a random item from a list but after several button taps and I get repeat items and sometimes the same item comes up two or three times in a row. What code can I use to stop repeating items in list unless the complete list has been run through?

Louis Braille was a French Educator who invented a tactile system of reading and writing for the blind and visually impaired in 1824. The system is called braille and it consists of raised dot codes that are used worldwide to read and write until this day.
Louis continued to work on his education and became an accomplished musician, writer, researcher, inventor, and teacher at the same school he studied at, the National Institute for Blind Youth. At age 20, he published the first braille book Method of Writing Words, Music, and Plain Songs by Means of Dots for Use by the Blind and Arranged for Them.
BBC/Tynker coding is a combination of the best in entertainment with the best in technology for learning. Using play and stories to enable learning is a long-established practice among educators. Using the Doctor Who story to inspire learners to code using the well-respected Tynker coding environment means that children learn in a non-threatening yet challenging environment that encourages success and learning through play.
Developed in the 1830s and 1840s by Samuel Morse and other inventors, the telegraph revolutionized long-distance communication. It worked by transmitting electrical signals over a wire laid between stations. In addition to helping invent the telegraph, the Morse code assigned a set of dots and dashes to each letter of the English alphabet and allowed for the simple transmission of complex messages across telegraph lines. In 1844, Morse sent his first telegraph message, from Washington, D.C., to Baltimore, Maryland; by 1866, a telegraph line had been laid across the Atlantic Ocean from the United States to Europe. The telegraph had fallen out of widespread use by the 20th century, replaced by the telephone, fax machine and Internet.
While scientists and inventors across the world began experimenting with batteries and the principles of electromagnetism to develop some kind of communication system, the credit for inventing the telegraph generally falls to two sets of researchers: William Cooke and Charles Wheatstone in England, and Samuel Morse, Leonard Gale and Alfred Vail in the United States.
Initially, the code, when transmitted over the telegraph system, was rendered as marks on a piece of paper that the telegraph operator would then translate back into English. Rather quickly, however, it became apparent that the operators were able to hear and understand the code just by listening to the clicking of the receiver, so the paper was replaced by a receiver that created more pronounced beeping sounds.
Among these improvements was the invention of good insulation for telegraph wires. The man behind this innovation was Ezra Cornell, one of the founders of the university in New York that bears his name. Another improvement, by the famed inventor Thomas Edison in 1874, was the Quadruplex system, which allowed for four messages to be transmitted simultaneously using the same wire.
It was during his time with the Sydney Morning Herald that Murray got the idea for the telegraphic typewriter. At the time, telegrams were transmitted by telegraphists using Morse code, then typed onto a telegram form which was then delivered by bicycle or on foot. Murray's idea was to use a typewriter to drive a device that translated each character of the text into a modified Baudot code. On the receiving end, another mechanism would print the coded characters on a paper tape, and/or make a perforated copy of the message. This system allowed the transmission of messages without need of operators trained in Morse code. At the time typists were being trained in great numbers using the QWERTY keyboard layout.[1]
Students learn how to design clean and reusable code that can be shared with a single classmate or the entire world. In the beginning of the unit, students are introduced to the concepts of parameters and return, which allow for students to design functions that implement an algorithm. In the second half of the unit, students learn how to design libraries of functions that can be packaged up and shared with others. The unit concludes with students designing their own small library of functions that can be used by a classmate.
N2 - Topics in source code can be identified using Latent Dirichlet Allocation (LDA) by receiving source code, identifying domain specific keywords from the source code, generating a keyword matrix, processing the keyword matrix and the source code using LDA, and outputting a list of topics. The list of topics is output as collections of domain specific keywords. Probabilities of domain specific keywords belonging to their respective topics can also be output. The keyword matrix comprises weighted sums of occurrences of domain specific keywords in the source code.

A common need for mobile application development by end-users or in computing education is to transform a sketch of a user interface into wireframe code using App Inventor, a popular block-based programming environment. As this task is challenging and time-consuming, we present the Sketch2aia approach that automates this process. Sketch2aia employs deep learning to detect the most frequent user interface components and their position on a hand-drawn sketch creating an intermediate representation of the user interface and then automatically generates the App Inventor code of the wireframe. The approach achieves an average user interface component classification accuracy of 87,72% and results of a preliminary user evaluation indicate that it generates wireframes that closely mirror the sketches in terms of visual similarity. The approach has been implemented as a web tool and can be used to support the end-user development of mobile applications effectively and efficiently as well as the teaching of user interface design in K-12.
