  1. Today’s STEM classrooms have expanded the domain of computer science education from a basic two-toned terminal screen to now include helpful Integrated Development Environments(IDE) (BlueJ, Eclipse), block-based programming (MIT Scratch, Greenfoot), and even physical computing with embedded systems (Arduino, LEGO Mindstorm). But no matter which environment a student starts programming in, all students will eventually need help in finding and fixing bugs in their code. While the helpful IDE’s have debugger tools built in (breakpoints for pausing your program, ways to view/modify variable values, and "stepping" through code execution), in many of the other programming environments, students are limited tomore »using print statements to try and "see" what is happening inside their program. Most students who learn to write code for Arduino microcontrollers will start within the Arduino IDE, but the official Arduino IDE does not currently provide any debugging tools. Instead, a student would have to move on to a professional IDE such as Atmel Studio or acquire a hardware debugger in order to add breakpoints or view their program’s variables. But each of these options has a steep learning curve, additional costs, and can require complex configurations. Based on research of student debugging practices[3, 7] and our own classroom observations, we have developed an Arduino software library, called Arduino Debugger, which provides some of these debugging tools (ex. breakpoints) while staying within the official Arduino IDE. This work continues a previous library, (redacted), which focused on features specific to e-textiles development boards. The Arduino Debugger library has been modified to support not only e-textile boards (Lilypad, Adafruit Circuit Playground) but most AVR and ARM based Arduino boards.We are also in the process of testing a set of Debugging Code Templates to see how they might increase student adoption of debugging tools.« less
  2. The e-textile landscape has enabled creators to combine textile materiality with electronic capability. However, the tools that e-textile creators use have been adapted from traditional textile or hardware tools. This puts creators at a disadvantage, as e-textile projects present new and unique challenges that currently can only be addressed using a non-specialized toolset. This paper introduces the first iteration of a wearable e-textile debugging tool to assist novice engineers in problem solving e-textile circuitry errors. These errors are often only detected after the project is fully built and are resolved only by disassembling the circuit. Our tool actively monitors themore »continuity of the conductive thread as the user stitches, which enables the user to identify and correct circuitry errors as they create their project.« less
