Please could you write a programming code for ARDUINO Nano - for a smart walking stick. Using these parts : An Arduino nano An Ultrasonic sensor(HCSR04) A 9-volt Battery A9-volt Battery connector A Buzzer Some jumper wires A vibration motor A switch The programming code should be similar to the one below, but please change it up and write comments throughout // defines pins numbers const int trigPin = 9; const int echoPin = 10; const int buzzer =11; const int motor = 13; // defines variables long duration; int distance; int safetyDistance; void setup() { pinMode(trigPin, OUTPUT); // Sets the trigPin as an Output pinMode(echoPin, INPUT); // Sets the echoPin as an Input pinMode(buzzer, OUTPUT); pinMode(motor, OUTPUT); Serial.begin(9600); // Starts the serial communication } void loop() { // Clears the trigPin digitalWrite(trigPin, LOW); delayMicroseconds(2); // Sets the trigPin on HIGH state for 10 micro seconds digitalWrite(trigPin, HIGH); delayMicroseconds(10); digitalWrite(trigPin, LOW); // Reads the echoPin, returns the sound wave travel time in microseconds duration = pulseIn(echoPin, HIGH); // Calculating the distance distance = duration * 0.034 / 2; safetyDistance = distance; if (safetyDistance <= 18) { digitalWrite(buzzer, HIGH); digitalWrite(motor, HIGH); } else { digitalWrite(buzzer, LOW); digitalWrite(motor, LOW); } // Prints the distance on the Serial Monitor Serial.print("Distance: "); Serial.println(distance);
