Design of Smart Blind Crutch System Based on Arduino

Abstract

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