Crash sensor (Left) Crash, bump, nudge, roller switch, sensor, Left
Price: $2.90
Availability: In Stock
Item #: DF-SEN0138-L -

    The Crash sensor (Left) is a miniature snap-action switch, also trademarked and frequently known as a micro switch. It is an electric switch that is actuated by very little physical force. Micro switches are very widely used; among their applications are appliances, machinery, industrial controls, vehicles, and many other places for control of electrical circuits. They are usually rated to carry current in control circuits only, although some switches can be directly used to control small...

      Gravity: Digital Line Tracking Sensor Digital Line Tracking Sensor
      Price: $5.90
      Availability: In Stock
      Item #: DF-SEN0017 -

        Line tracking is the most basic function of a smart mobile robot. It is one of the easiest ways for a robot to successfully and accurately navigate. The Digital Line Tracking Sensor will guide your robot by telling white from black quickly and accurately, via TTL signal. With a drawn path and good programming, you can ensure results that are far more consistent than if the robot was simply told where to go without any reference. You can combine several line following sensors with other ranged...

        LED Voltage Meter (Red) Voltmeter, LED, Voltage, Meter, Red, voltimeter, dfrobot
        Price: $6.80
        Availability: In Stock
        Item #: DF-DFR0130-R -

          This is a standalone DC Voltmeter. It measures 3V-30V with ±1% accuracy. Best suited for battery level display. Just apply two wires on the power without any extra circuitry or components, it gives the reading straight away. Easy to use, and is a good companion to robotic applications.

          2A Dual Motor Controller Motor, Driver, 2A, Dual, Controller
          Price: $17.05
          Availability: In Stock
          Item #: DF-DRI0002 -

            This is a 4.8-46V, 2A Dual Motor Controller which is the revised version of the DF-MDV1.0. Its performance has been improved greatly. It can bear larger current due to the increased heatsink dissipation. It is easy to control, using LGS's outstanding high-power motor driver chip, the L298N. This chip allows for direct drive of two bi-directional DC motors, and incorporates high-speed short diodes for protection. Drive current up to 2A per motor output. The driver uses a broad-brush design to...
