Hi All
I am relatively new to Arduino and I am using this for my final year project on a Visitor Control Access System.
I manage to make 2 separate coding works:
- Barcode Scanner
- Control Access System with Servo, push buttons and Red/Green LEDs (When green LED is ON, servo opens, ultrasonic sensor will sense for any obstruction before Green LED goes off and servo closes)
I am trying to combine both of the 2 codes to build a visitor control access system when a visitor will scan its ID to open the servo, pass through and servo closes.
I uploaded the above 2 codes and the combined version which I am currently stuck at for weeks.
Code 1: Control Access System
#include <Servo.h>
Servo s1;
int ledPinGreen = 10; // Green LED connected to digital pin 10
int ledPinRed = 11; // Red LED connected to digital pin 11
int ledPinBlue = 12; // blueled entry US sensor
int inputPin1 = 3; // pushbutton pin for green
int pos = 0;
int ledPinBlue2 = 5; // blueled2 exit US sensor
int inputPin2 = 9;
int UStrigPin = 13; //entry US sensor output
int USechoPin = 8; //entry US sensor input
long duration;
int distance;
int UStrigPin2 = 7; // exit US sensor output
int USechoPin2 = 6; // exit US sensor input
long duration2;
int distance2;
void setup (){
s1.attach(4);
pinMode(ledPinGreen, OUTPUT); // sets the pin as output
pinMode(ledPinRed, OUTPUT); // sets the pin as output
pinMode(inputPin1, INPUT); // entry set
pinMode(ledPinBlue, OUTPUT);
pinMode(inputPin2, INPUT); // exit set
Serial.begin(9600);
pinMode(UStrigPin, OUTPUT);
pinMode(USechoPin, INPUT);
pinMode(UStrigPin2, OUTPUT);
pinMode(USechoPin2, INPUT);
}
void loop(){
long dist;
digitalWrite(ledPinRed, HIGH); // turn the Red LED on (LOW is the voltage level)
if (digitalRead(inputPin1) == LOW) { // read the state of the pushbutton1 value
for (pos = 0; pos < 90; pos +=1){
s1.write(pos);
delay(1);
digitalWrite(ledPinRed, LOW); // turn the Red LED off (LOW is the voltage level)
digitalWrite(ledPinGreen, HIGH); // turn the Green LED on (HIGH is the voltage level)
delay(3000);
digitalWrite(UStrigPin,HIGH); //output
delay(1000);
digitalWrite(UStrigPin,LOW); //output
duration=pulseIn(USechoPin,HIGH);
distance = duration*0.034/2;
dist = distance;
Serial.println(distance);
if (dist <= 15) {
digitalWrite(ledPinBlue,HIGH);
}
else {
digitalWrite(ledPinBlue,LOW);
for (pos = 0; pos < 90; pos +=1){
s1.write(pos);
delay(1);
digitalWrite(ledPinRed,HIGH);
digitalWrite(ledPinGreen,LOW);
}
}
}
}
if (digitalRead(inputPin2) == LOW) { // read the state of the pushbutton1 value
for (pos = 0; pos < 90; pos +=1) {
s1.write(pos);
delay(1);
digitalWrite(ledPinRed, LOW); // turn the Red LED off (LOW is the voltage level)
digitalWrite(ledPinGreen, HIGH); // turn the Green LED on (HIGH is the voltage level)
delay(3000);
digitalWrite(UStrigPin2,HIGH); //output
delay(1000);
digitalWrite(UStrigPin2,LOW); //output
duration2 = pulseIn(USechoPin2,HIGH);
distance2 = (duration2*0.034)/2;
dist = distance2;
Serial.println(distance2);
if (dist <= 15) {
digitalWrite(ledPinBlue2,HIGH);
}
else {
digitalWrite(ledPinBlue2,LOW);
for (pos = 0; pos < 90; pos +=1){
s1.write(pos);
delay(1);
digitalWrite(ledPinRed,HIGH);
digitalWrite(ledPinGreen,LOW);
}
}
}
digitalWrite(ledPinGreen, LOW);
}
}

if(Usb.Init()==-1) Serial.println("OSC did not start.");
else Serial.println("Barcode Ready");
Hid.SetReportParser(0,(HIDReportParser*)&Prs); //Change "Keyboard" for "Hid"
s1.attach(4);
pinMode(ledPinGreen, OUTPUT); // sets the pin as output

pinMode(UStrigPin2, OUTPUT);
pinMode(USechoPin2, INPUT);
}
void loop()
{
digitalWrite(ledPinRed, HIGH);
(Usb.Task());
}
How can I code so that when the barcode scanner scanned an ID, it will turn off RED Led, trigger the Green LED to turn on?
Any help will be greatly appreciated! Thank you in advance and Cheers!
