    Could you use two of these as transmitters, sending messages to a robot with a receiver, to create a positioning system using trigonometr and the time taken for each message to arrive from the anchor/transmitter?

    • @PlayfulTechnology
      @PlayfulTechnology  8 місяців тому +1

      You _could_, but you'd need to have a very accurate timestamp synchronised between the devices, or else a multiple roundway-trip at which each device records their own timestamp, and then compares that to the time at which the response is received back.

    • @willwahlberg1890

      The antennas are necessary. Otherwise the modules will only be able to communicate if they are directly next to each other. The antennas are used for increasing range.
