A man playing a version of the wire loop game. A wire loop game, or buzz wire, is a game which involves guiding a metal loop (a 'probe') along a serpentine length of wire without touching the loop to the wire. [1] The loop and wire are connected to a power source in such a way that, if they touch, they form a closed electric circuit.
A buzzer or beeper is an audio signaling device, [1] which may be mechanical, electromechanical, or piezoelectric (piezo for short). Typical uses of buzzers and beepers include alarm devices , timers , train and confirmation of user input such as a mouse click or keystroke.
European Siren for fire detection system. A fire alarm notification appliance is an active fire protection component of a fire alarm system.A notification appliance may use audible, visible, or other stimuli to alert the occupants of a fire or other emergency condition requiring action.
An electric buzzer uses a similar mechanism to an interrupter bell, but without the resonant bell. They are quieter than bells, but adequate for a warning tone over a small distance, such as across a desktop. A buzzer or beeper is an audio signalling device, which may be mechanical, electromechanical, or piezoelectric.
A specialist technician who installs outside plant wiring (overhead circuits, power transmission lines). Litz wire A kind of stranded wire used to minimize losses in coils. load flow study A mathematical prediction of the flow of electric power in a network, based on a model of the actual or proposed system; necessary for planning of electrical ...
This corresponds to wired AND in active-high logic, or to wired OR in active-low logic, and allows multiple inputs to share the same output wire. Main article: Wired logic connection Another advantage is that more than one open-collector output can be connected to a single line.
An Arduino-compatible board designed for auto-piloting and autonomous navigation of aircraft, cars, and boats. It uses GPS for navigation and thermopile sensors or an IMU for stabilization. ArduIMU [142] An Arduino-compatible board designed for inertial measurement and inertial navigation of aircraft, cars, and boats.
The indicator may be an electric light or a buzzer. [1] This led to the term "buzzing out a circuit" (which means to test for continuity) [ 3 ] Audible continuity buzzers or beepers are built into some models of multimeter , and the continuity setting is normally shared with the ohmmeter setting.
