touch sensor and 16x2 LCD

Projects Programming
1

hello;
I have successfully connected the touch sensor to the arduino but I would like to put a screen that displays the number of times I touch the touch sensor.

can someone please help me ?

Have you tried the example programs from the LCD library ?

Nope; I'm going to try

Don't try to write the program all in one go. Start small and write portions and test them You say

I have successfully connected the touch sensor to the arduino

You have connected it, but can you read it and display its state on the Serial monitor ?
Can you detect when its state changes ?
What counts as a change of state anyway ?
Maybe take a look at the StateChangeDetection example in the IDE

I have programmed the touch sensor alone and yes; the serial monitor indicates whether or not I touch the touch sensor. However, I have no Idea for the program of my LCD. I want the program to indicate the number of times I find the sensor.

I have no Idea for the program of my LCD.

Try the LCD library examples first

I want the program to indicate the number of times I find the sensor.

Start by adding 1 to a counter when the reading from the sensor changes from not to touched to touched. Did you look at the example to detecting a change of state as I suggested ?

Please post your code that shows the sensor state in the Serial monitor

Ok; thanks I zill see

int ledPin = 13; 
 
void setup() {
  Serial.begin(9600);
  pinMode(ledPin, OUTPUT);  
  pinMode(ctsPin, INPUT);
}
 
void loop() {
  int ctsValue = digitalRead(ctsPin);
  if (ctsValue == HIGH){
    digitalWrite(ledPin, HIGH);
    Serial.println("TOUCHED");
  }
  else{
    digitalWrite(ledPin,LOW);
    Serial.println("not touched");
  } 
  delay(500);
  
}

If you look at the example I suggested you should be able to see how to detect when the sensor state changes from LOW to HIGH. When that occurs add 1 to a counter and print it
