Question

#include Servo servo; int const trigPin = 9; int const echoPin = 8; #define red 5 #define green 6 void setup() { pinMode(trigPin, OUTPUT); pinMode(echoPin, INPUT); pinMode(red,OUTPUT); pinMode(green,OUTPUT); servo.attach(10); } void loop() { int duration, distance; digitalWrite(trigPin, HIGH); digitalWrite(trigPin, LOW);// Measure the pulse input in echo pin duration = pulseIn(echoPin, HIGH);// Distance is half the duration devided by 29.1 (from datasheet) distance = (duration/2) / 29.1;// if distance less than 0.5 meter and more than 0 (0 or less means over range) if (distance = 0) { servo.write(60); digitalWrite(green,HIGH); digitalWrite(red,LOW); delay(200); } else { servo.write(10); digitalWrite(red,HIGH); digitalWrite(green,LOW); delay(80); } } TASK: create a flowchart using this code, showing the input, output and the conditions on the loop. Lastly, the flowchart must return if ever the conditions have met or not
