  • Ultrasonic Distance Sensor for Bit:Bot (BitBot) (BITSON)
    Ultrasonic Distance Sensor for Bit:Bot

    NB. Bit:Bot not included

    Ready-Soldered, just attach to your Bit:Bot with the screws provided and off you go.

    Use Microsoft PXT (or MicroPython with some awkward code) to read the distance to an obstacle, then program your Bit:Bot to avoid it.

    Both Ping and Echo signals are on the same pin (Pin 15)

    This accessory is available in 2 flavours:
    1. With the ultrasonic sensor soldered directly to the PCB
    2. With a socket soldered on the PCB that you can plug the sensor into
    The sensor soldered into the PCB is much more robust and reliable, but has a big drawback in that you cannot access the micro-USB connector on the micro:bit unless you either remove the micro:bit or use a right-angled USB lead

    The socketed version allows most USB leads to access the micro:bit, but it isn't as robust.

    • Rubber grommet with 10mm internal diameter - ideal for Sharpie felt tips and other pens
    • Easily fitted onto the two screws for the battery support pillars in seconds

    This accessory is available in 2 flavours:
    1. Plain PCB with rubber grommet for maximum economy
    2. Fitted with 8 bright white LEDs to produce a glow-ring effect on the top and lighting the drawing below**

    * CrumbleBot must use 3xAA battery holders as this is fitted to the bottom of the battery support pillars
    ** Powered LEDs on CrumbleBot requires the "wire-free" battery holder system

  • Ultrasonic Distance Sensor (Static) CrumbleBot Addon (BOTSONIC)
    Static Ultrasonic Distance Sensor for CrumbleBot

    This a simple, screw-together addon for all versions of CrumbleBot. Using the 2 mounting holes at the front, together with the power supply extension pieces (included) you can easily add distance sensing to your CrumbleBot.

    Using a single Croc Clip for the sensor reading and Crumble Software 25.2 or later, you can check if the CrumbleBot is about to hit an obstacle then avoid it if necessary.

    No soldering is required, and the kit can be assembled in a few minutes using only a small philips (cross head) screwdriver

    Contents:

  • Ultrasonic Distance Sensor (Panning) CrumbleBot Addon (BOTSONPAN)
    Panning Ultrasonic Distance Sensor for CrumbleBot

    This a simple, screw-together addon for all versions of CrumbleBot. Using the 2 mounting holes at the front, together with the power supply extension pieces (included) you can easily add distance sensing to your CrumbleBot.

    This version of the kit includes a servo to allow you to move the ultrasonic sensor left and right, using the inbuilt Crumble software commands.

    Using two Croc Clips, one for the servo and one for the for the sensor reading, as well as Crumble Software 25.2 or later, you can check if the CrumbleBot is about to hit an obstacle then avoid using a more sophisticated algorithm than just a static (non-moving) sensor. Of course, you can simply not move the sensor and use the simple software shown in the static sensor listing

    The program shown above detects an obstacle within 15cm, then looks left and right to see which direction has the closest obstacle. It then reverses out of the way of the current obstacle, before turning towards the direction with most space to move.

    No soldering is required, and the kit can be assembled in a few minutes using only a small philips (cross head) screwdriver

    Contents:
    • Ready assembled ultrasonic PCB (moving)
    • Ready assembled servo PCB (static)
    • Servo, complete with various fixings
    • Red positive power extension
    • Black negative power extension
    • 2 x M3 25mm hex pillars
    • 6 x M3 6mm screws
    • 2 x M3 nuts
    • 4 way female-female 10cm cable to connect the sensor to the static servo PCB
