Product Description

Kitronik Access:Bit for the BBC micro:bit

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.

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.

Awesome service with super fast delivery. The chat option really helped me choose the products, know they were in stock and would be delivered in time. The items were posted the same day and I couldn't believe it when they arrived from Perth to Melbourne in 3 days! Thanks for your wonderful support - our students were able to complete their robotic projects in time.
