E-textiles, which embed circuitry into textile fabrics, blend art and creative expression with engineering, making it a popular choice for STEAM classrooms [6, 12]. Currently, e-textile development relies on tools intended for traditional embedded systems, which utilize printed circuit boards and insulated wires. These tools do not translate well to e-textiles, which utilize fabric and uninsulated conductive thread. This mismatch of tools and materials can lead to an overly complicated development process for novices. In particular, rapid prototyping tools for traditional embedded systems are poorly matched for e-textile prototyping. This paper presents the ThreadBoard, a tool that supports rapid prototypingmore »
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 »
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 »
When learning to code a student must learn both to create a program and then how to debug said program. Novices often start with print statements to help trace code execution and isolate logical errors. Eventually, they adopt advance debugger practices such as breakpoints, "stepping" through code execution, and "watching" variables as their values are updated. Unfortunately for students working with Arduino devices, there are no debugger tools built into the Arduino IDE. Instead, a student would have to move onto a professional IDE like Atmel Studio and/or acquire a hardware debugger. Except, these options have a steep learning curvemore »
STEAM curriculums are widely implemented in K-12 schools, as part of the effort to promote computational thinking skills. This, together with increased accessibility of electronic components and kits, has opened the door for novices to engage in physical computing projects. Debugging these projects challenges students to learn and apply electrical concepts together with programming skills. Multimeter, the most common tool for measuring electric circuits, is placing a very high bar for novices to use. This paper presents a work in progress toward the development of a low-floor multimeter. The tool is designed to be used by high-school students with nomore »
