Howtoons Electrical Problems Electrical problems are problems with either the design or construction of your electrical circuits. These are physical problems that you’ll need to fix by hand with scissors, a needle, thread, fabric, and glue. The next several pages provide examples of common electrical problems, information about how to find them, and step-by-step instructions for fixing them. ELECTRICAL PROBLEMS COVERED IN THIS SECTION • loose connections • short circuits • reversed polarity Loose connections occur when the thread that is stitched through a component (like an LED, speaker, LilyTiny, or Protoboard) is too loose. If the thread is too loose, there will not be a consistent electrical connection between the thread and the component. symptoms If there is a loose connection in your project, parts of your project will only work some of the time. checking your project for loose connections Gently bend and stretch your project. To fix loose connections, thread your needle with conductive thread.

Canadian Valley Professional Development Network Calendar Electronics Measuring Stuff with a Multimeter A multimeter is an electronics testing device that, um, tests multiple things, including resistance, voltage, and current. Using certain multimeter models, you can test to be sure that components — such [more…] Electronics Basics: Using a Breadboard A breadboard is a rectangular plastic box filled with holes, which have contacts in which you can insert electronic components and wires. What Is Soldering and How Do You Use Solder Tools? Soldering (pronounced "soddering") involves a material called solder that melts when placed on a hot object; the melted solder cools and forms a bond between two items. Turning Electricity On and Off You've scrounged around your growing electronics bin and come up with wires to connect a circuit together and batteries to power the circuit. Steps to Great Car Audio Sound It takes a lot to create a good car audio system. Ten (Or So) Cool Electronics Testing Tool Tips Okay, so you're ready to graduate to the electronics big time.

For example, you bounce up and down on a Pogo Stick. The pager motor does the same thing with the toothbrush head—it bounces it up and down. To move forward on a Pogo Stick, you tilt it forward while bouncing. ¿Sabías esto? El robot con cerdas es muy parecido a un cangurín tipo pogo.
