Blind Stick Obstacle Detector Kit with Arduino Uno – 180° Ultrasonic Radar Display

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

Design a portable electronic cane that scans the environment and paints a real-time radar view on a small OLED screen. This kit takes an accessibility concept — a blind person’s walking stick that detects obstacles — and replaces the audio feedback with a crisp polar plot showing distance arcs and target blips. Originally conceived as an assistive aid, the project becomes an engaging way to learn sensor integration, servo kinematics, and display graphics coding.

What You'll Build

You’ll assemble a handheld module where an HC-SR04 ultrasonic sensor sits on an SG90 micro servo. The servo sweeps 180 degrees, continuously measuring distances. The 0.96-inch OLED maps those readings into a radar-style polar chart: you’ll see a scanning beam line, concentric distance rings, and dots that appear where obstacles stand. It’s like a miniature ship radar, right in your palm, and the perfect launchpad into assistive technology prototyping.

What You'll Learn

• Interfacing HC-SR04 ultrasonic sensor with Arduino Uno and timing pulse measurement
• Servo sweep control and mapping angle to effective distance
• OLED graphics programming using the U8g2 library to draw polar grids and blips
• Real‑time data processing and visualization on a compact display
