Design of Smart Blind Crutch System Based on Arduino

The blind used traditional crutch to walk on the track in past. With increase of and complexity situation road, simple cannot give enough security blind. needs improvement active obstacle avoidance night safety meet demand. In this paper, a smart is designed. ultrasonic ranging sensor, laser color photosensitive resistance, buzzer vibrator are linked together with Arduino microcontrollers realize reminder, lane traffic light recognition, glowing when dim, which integrated into facilitate travel tests show that accurate reminding obstacles front, recognizing lanes ground lights, sensitive luminous induction at night. Compared crutch, more guaranteed especially This also provides referenced for crutch.
