Follow the circuit diagram and make the connections as shown in the image given below. To design Blind Walking Stick Using Arduino & Ultrasonic Sensor HC-SR04, make the following connections as shown in the connection diagram below. It essentially gives your Arduino eyes / spacial awareness and can prevent your robot from crashing or falling off a table. In circuit connections Ultrasonic sensor module’s “trigger” and “echo” pins are directly connected to pin 18(A4) and 19(A5) of arduino. To use IR sensor we connect Vcc of sensor to Positive terminal of battery , and Gnd pin of sensor … and if duration is not zero the distance will be calculated using the function distance = duration / 58. “Electronic Clinic” is an Electrical and Electronics Engineering community built and run by professional electrical engineers and computer experts. A 16x2 LCD is connected with arduino in 4-bit mode. The Obstacle detection range can be adjusted in the programming. TRIG pinthis pin receives the control signal (pulse) from Arduino.
