The ACCESS:bit is a bolt-on/clip-on board for the BBC micro:bit that simulates an access barrier. It includes a servo-driven barrier arm, an integrated 3×AAA battery cage with on/off switch, and a buzzer for sound effects. The ACCESS:bit joins the Kitronik family of transportation micro:bit accessories alongside the STOP:bit and LAMP:bit.
Once the micro:bit is fitted, its LED matrix remains fully visible and can display warning signals, stop/go symbols, or act as a light sensor for autonomous barrier actions. The board connects via the supplied M3 countersunk screws or crocodile clips.
Key Features
- Access Barrier Simulation – Servo-driven barrier arm for realistic movement
- Integrated Battery Cage – 3×AAA with on/off switch (batteries not included)
- Built-in Buzzer – Sound effects for barrier open/close actions
- LED Matrix Visible – micro:bit display remains accessible for signals and symbols
- MakeCode Extension – Custom Kitronik code blocks available in the MakeCode editor
- Flexible Connection – Attach via M3 screws or crocodile clips
- Dimensions – 89 mm (H) × 125 mm (W with barrier extended) × 30 mm (D with servo)
Ideal For
- Transportation and traffic simulation projects
- STEM education and classroom activities
- Combining with STOP:bit and LAMP:bit for larger traffic systems
Package Contents
- 1× ACCESS:bit board with integrated battery cage
- 1× 180° servo
- 1× Access barrier arm
- 5× M3 countersunk screws and M3 nuts
Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- servo
- A servo is a motor with built-in position control, usually told to move to a specific angle by a control signal. It matters when you need repeatable movement, such as steering, arms, flaps, or linkages, rather than continuous spinning.
