Kitronik Ultrasonic Distance Sensor HC-SR04 5V Version

The STOP:bit for the BBC micro:bit is the ultimate upgrade for traffic light/pedestrian crossing projects. Not only does it make coding the project a breeze, but the board is also supplied pre-assembled so you don't even need to fire up the soldering iron. Love it or hate it, variations of the pedestrian crossing project have been around for decades. When I did mine, it was on a 6502 EMMA board and coded with Assembly and it also included a level crossing. Thankfully, tapping low-level programming languages into a hexadecimal keypad is now a thing of the past. The Kitronik STOP:bit is a purpose-built accessory that can only lead to a more enjoyable project with a nicer looking end result.

Micro:bit V2 is a tiny, programmable computer board designed to teach kids and beginners about coding, electronics, and robotics. The board features a range of sensors, buttons, and LED lights that can be programmed using various programming languages and visual programming tools.

Now includes both a speaker and microphone as well as many of the same great features students have used for years. It's easier than ever to use sound and touch to get creative in the classroom.

Using the micro:bit V2, students will be able to sense and react to sound with the built-in microphone and play sound with the built-in speaker while coding in MakeCode, Python, or Scratch!

The ACCESS:bit is a bolt-on/clip-on board for the BBC microbit that simulates an access barrier. It includes a switch for turning the integrated 3xAAA battery supply on and off and also a buzzer for sound. The ACCESS:bit joins the family of transportation/pedestrian crossing micro:bit accessories, that also includes; the STOP:bit and LAMP:bit.

The ACCESS:bit is supplied with a single servo, a barrier, and all of the required fixings. Once the microbit has been fitted to the ACCESS:bit its LED matrix is fully visible and therefore can be used to display warning signals, stop/go symbols or as a light sensor for autonomous actions.

The ACCESS:bit has been designed to allow for connection to the micro:bit via the supplied M3 countersunk screws or via crocodile clips. For pinout information, please refer to the Datasheet below.

Kitronik has also produced a set of custom MakeCode editor blocks that make it possible to simplify the task of coding, thus opening up this activity to younger students.

To add the custom blocks to the MakeCode menu, select the cog in the top right of the editor. Then, select Extensions from the drop down menu. This will bring up the search box, search for Kitronik. Now, select the ACCESS:bit tile and the blocks will be added to the editor.

Note: This kit requires some mechanical assembly.

Features:

The ACCESS:bit is an accessory for the BBC micro:bit that simulates an access barrier.

It features and on/off switch, integrated battery cage and buzzer for sound.

The micro:bit can bolt-on/clip-on to the board.

It follows the same aesthetic as the STOP:bit and LAMP:bit.

It can be used in conjunction with the STOP:bit and LAMP:bit for larger projects.

Kitronik have created custom code blocks for the MakeCode Editor that are available as an Extension to the editor.

Contents:

1 x ACCESS:bit with integrated battery cage.

5 x M3 Countersunk screws and M3 nuts.

1 x 180 degree servo.

A single access barrier.

Dimensions::

Height: 89mm.

Max Width (with barrier fully extended): 125mm.

Max Depth (with servo affixed): 30mm.

PCB Thickness: 1.6mm.

The MI:sound board is a speaker board for the BBC microbit. It features on-board; speaker, CR2032 battery holder, thumbwheel volume control and an easy access on/off switch. The MI:sound board can either be powered by the CR2032 battery (provided) or via the micro:bit USB or JST connections. It has been designed to work with micro:bit V1 and micro:bit V2.

The speaker on MI:sound can be used in conjunction with the micro:bits onboard speaker or instead of. The micro:bit speaker can be turned off as there is a command/block for that in the MakeCode editor. Why would you want to? Volume! MI:sound's speaker is loud, and the potentiometer gives you control over its volume without the need to head back into the code. Super convenient!

To use the MI:sound speaker board, the BBC micro:bit should be attached using the supplied bolts, spacers and nuts. Only Pin 0, 3V and GND need to be connected. Crocodile clips can also be used.

When assembled, the MI:sound board is connected directly to the 3V, GND and P0 connections on the micro:bit. The 3V and GND connections provide power to the micro:bit and the built in buzzer is connected to P0, which is the default output pin when using the audio functions in the MakeCode software. The board has an easy to access on/off switch, which makes it easy to turn a project on and off.

Like the MI:power board, MI:sound offers an elegant solution for micro:bit projects on the move. Both boards provide power to micro:bit, feature an on/off switch and allow you to output sound. Sound though is a much bigger feature on the MI:sound board. Where the MI:power board features a buzzer, MI:sound has an actual speaker with a thumbwheel volume control. Not only is the speaker more versatile than a simple sounder, it is also much much louder. So, in brief; the MI:power board is more compact and MI:sound is better for projects where sound is an integral part of the project.

Features:

Power your BBC micro:bit from a stylish PCB.

It features an on-board speaker and it's loud!

There is a thumb wheel operated potentiometer volume control.

There is an onboard CR2032 battery holder.

The board features easy access on/off switch.
