Help with coding - IRSensor with LED

Projects Programming
1

Hello,

I need some help with coding on my Arduino Uno board. I am using IRSensor as the controller to my LEDs, the idea is that when the sensor senses the object within a certain proximity, I want the light to turn on or off. When the light is off, with approaching it you can turn it on, and when the light is on, Vise Versa.
Here is the code I've written, when I tried it, the light will turn off but it won't turn back on.

Please let me know if you have a solution for this. Thank you so much.

int IRSensor = 2; // connect ir sensor to arduino pin 2
int LED = 12; // conect Led to arduino pin 13
int timeNumber = 0;
boolean timeState = true;

void setup()
{
 pinMode (IRSensor, INPUT); // sensor pin INPUT
 pinMode (LED, OUTPUT); // Led pin OUTPUT
}

void loop()
{
 if (timeState == false){
   digitalWrite(LED, LOW);
 }else{
   digitalWrite(LED, HIGH);
 }

 int statusSensor = digitalRead (IRSensor);

 if (statusSensor == 1){
   timeNumber++;
   if(timeNumber == 9){
     if(timeState == false) timeState = true;
     if(timeState == true) timeState = false;
     timeNumber = 0;
   }
 }
 
 delay(100);
}

I think I see your problem!

if(timeState == false) timeState = true; 
if(timeState == true) timeState = false;

So timeState equals false, it makes it true, next line timeState equals true so it makes it equal false! (back to where you started)

You need to do something like this:

if timeState == false {
timeState = true; 
} 
else{
timeState = false;
}

(Untested code)

Thanks,
