Hey... Im new to this arduino project.
I have tried to make an IR motion sensor to display at 7 segment digit using this code below.
Now Im trying to make it detect two motion to display 1 time at 7 segment digit.
I have tried but fail multiple times.
Can anyone help me with the code. Thank you.
const int a = 11; //For displaying segment "a"
const int b = 10; //For displaying segment "b"
const int c = 9; //For displaying segment "c"
const int d = 8; //For displaying segment "d"
const int e = 7; //For displaying segment "e"
const int f = 12; //For displaying segment "f"
const int g = 13; //For displaying segment "g"
bool IRsensor = false;
const int IRsensorPin = 5;
// Variables will change:
int IRsensordetect = 0; // counter for the number of button presses
int IRsensorState = 0; // current state of the button
int lastIRsensorState = 0; // previous state of the button
void setup() {
// put your setup code here, to run once:
pinMode(a, OUTPUT); //A
pinMode(b, OUTPUT); //B
pinMode(c, OUTPUT); //C
pinMode(d, OUTPUT); //D
pinMode(e, OUTPUT); //E
pinMode(f, OUTPUT); //F
pinMode(g, OUTPUT); //G
pinMode( IRsensorPin , INPUT_PULLUP );
Serial.begin(9600);
displayDigit(IRsensordetect);
}
void loop() {
IRsensorState = digitalRead(IRsensorPin);
// compare the buttonState to its previous state
if (IRsensorState != lastIRsensorState) {
// if the state has changed, increment the counter
if (IRsensorState == LOW) {
// if the current state is HIGH then the button went from off to on:
IRsensor = true;
IRsensordetect++;
if( IRsensordetect > 9) IRsensordetect = 0 ;
Serial.println("on");
} else {
// if the current state is LOW then the button went from on to off:
Serial.println("off");
}
// Delay a little bit to avoid bouncing
delay(50);
}
// save the current state as the last state, for next time through the loop
lastIRsensorState = IRsensorState;
if( IRsensor ){
turnOff();
displayDigit(IRsensordetect);
}
}
void displayDigit(int digit)
{
//Conditions for displaying segment a
if(digit!=1 && digit != 4)
digitalWrite(a,HIGH);
//Conditions for displaying segment b
if(digit != 5 && digit != 6)
digitalWrite(b,HIGH);
//Conditions for displaying segment c
if(digit !=2)
digitalWrite(c,HIGH);
//Conditions for displaying segment d
if(digit != 1 && digit !=4 && digit !=7)
digitalWrite(d,HIGH);
//Conditions for displaying segment e
if(digit == 2 || digit ==6 || digit == 8 || digit==0)
digitalWrite(e,HIGH);
//Conditions for displaying segment f
if(digit != 1 && digit !=2 && digit!=3 && digit !=7)
digitalWrite(f,HIGH);
//Conditions for displaying segment g
if (digit!=0 && digit!=1 && digit !=7)
digitalWrite(g,HIGH);
}
void turnOff()
{
digitalWrite(a,LOW);
digitalWrite(b,LOW);
digitalWrite(c,LOW);
digitalWrite(d,LOW);
digitalWrite(e,LOW);
digitalWrite(f,LOW);
digitalWrite(g,LOW);
