Teach Kids Accessibility Tech with the Micro:bit Blind Navigator Kit

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

With this kit, your child will build a portable device that beeps faster as obstacles get closer-just like the navigation tools used by visually impaired people. It's a fun, screen-free way to explore the engineering behind accessibility, while learning real-world coding and electronics.

What You'll Build

Your young maker will assemble a circuit using a BBC Micro:bit, HC-SR04 ultrasonic sensor, and piezo buzzer, connected with colour-coded crocodile clips. They'll then program the Micro:bit to read distance values and map them to sound frequencies, so the beep speeds up as a hand, wall, or furniture draws near. The finished gadget can be held like a torch or worn on a cycle helmet for a fun tech demo.

What You'll Learn

• Measure distance accurately with an HC-SR04 ultrasonic sensor
• Code conditional logic in MakeCode blocks to link sensor data to sound output
• Understand how echolocation and assistive devices work in the real world
• Build a complete, battery-powered circuit without soldering, using crocodile clips

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is designed for curious kids aged 8-10 who have never tried electronics before. It's perfect for CBSE Class 4-6 students exploring practical science, ATL Tinkering Lab sessions on empathy-driven innovation, and parents seeking a weekend activity that blends technology with social awareness. B.Tech ECE/EEE students can also use it as a rapid prototype for accessibility hackathons.

Built and Backed by Compoden

Every Compoden kit ships with an AI build companion trained on this exact project - accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
