Study on a new type of intelligent blind-guiding stick

Based on triangle metering distance principle of infrared detectors and photoelectric sensor technology,a new type of intelligent blind-guiding stick is designed.The core of the device is the Arduino singlechip,with three infrared detectors detecting the obstacle distance data from different directions,which is read,operated and optimized by the singlechip.Then,the Arduino singlechip control buzzer prompts and MP3 voice prompts to tell the blind walker the correct direction.Due to the timeliness and accuracy of the alarm system,this blind-guiding stick can guide blind walkers to bypass the obstacles and walk safely and quickly.
