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 is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- 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.
