  • Meet TELEBOT, the terrifying telepresence robot
    by Arduino Team (Arduino Blog) on 1 June 2020 at 19:23

    The Internet has been perhaps more important than ever to keep us connected these days. Available technology, however, apparently wasn’t good enough for brothers Hunter and Josh Irving, who built their own telepresence robot using parts on-hand during their own two-person hackathon. The robot they came up with, dubbed TELEBOT, features a partially 3D-printed face along

  • Difference Between Duty Cycle, Frequency And Pulse Width

  • What Is a Magnetic Switch And What Are Its Applications?
    by EFY Team (Electronics For You) on 1 June 2020 at 11:06

    A magnetic switch is an electrical switch that makes or breaks contacts in the presence of a magnetic field. That is, the switch remains actuated as long as a strong magnetic field is present and opens when the field is removed. Examples of magnetic switches include reed switches, Hall effect sensors and electromechanical relays.
