This is a super mini voltmeter with 0.28 inch LED display. It has reverse connect protection (though it is advisable to mind your wiring). When voltage is less than 10V, two decimal places will be shown. When voltage is more than 10V, one decimal place will be shown. This voltmeter would be great for a battery readout on your next robot, or generally useful for a retro readout panel!

The Grove - Hall Sensor measures the Hall Effect, which is a production of a voltage difference across an electrical conductor, transverse to an electric current in the conductor, as well as a magnetic field perpendicular to the current. The output of the continuous-time switch Hall sensor on this Twig switches low and turns on when a magnetic field (south polarity) perpendicular to the Hall sensor exceeds the BOP threshold, and it switches high (turns on) when the magnetic field disappears. ...
