Introduction: Blind Guider

Blind Guider is a wearable device aims to help blind people to understand their surroundings.

  • It detects the presence of obstacles in front of the user without the need of physical contact.
  • It gives a flashing light to inform surrounding people if the user is walking towards them.
  • It uses a built in compass to guide users to the directions they need.

Blind Guider uses vibration as an indicator of objects in the way, or in the compass mode, of directions. We hope that Blind Guider could provide protection to the visually impaired, and make their life easier.

Step 1: Download 3D Model and Source Code

Step 2: Solder All Components With Wires.

Ultrasonic sensor, vibration motor, compass, highpower LED, switches. Note that we also need resistors with LED and switches.

Step 3: ​Attach All Components to Arduino

Attach all components to Arduino, see pins in code.

Step 4: Import Code to Arduino

Step 5: Attach All Components, Including Arduino and Battery, to 3D Printed Case.

Step 6: Add Velcro Tape, Cover Device With Cloth.
