Introduction: The ACCESS:bit is a bolt-on/clip-on board for the BBC

micro:bit simulating an access barrier. The ACCESS:bit has been designed to

have the ability to drive a single servo with barrier and a buzzer for sound.

It Includes a switch for turning the integrated 3xAAA battery supply on and

off. Fitted on the PCB is a regulated 3V supply to power the BBC micro:bit,

this connection is through the 5 pin BBC micro:bit connection pads

The ACCESS:bit has been designed so that the BBC micro:bit LED display can

be used to recreate warning lights, display stop and go symbols or be used

for light sensor activation.

Connection: 5 x M3 countersunk screws

and M3 nuts allow the user to bolt the

ACCESS:bit onto the BBC micro:bit.

Crocodile clips also can be used

between the pads on the ACCESS:bit

and the matching pads on the BBC

micro:bit.
