No, with the 4 pin, they have split the data lines to Echo and Trigger, instead of a single line. The 3 pin code will work, you just need to tweak it to work with trigger and echo. HINT: one is input and the other is output.

There are PLENTY of RTC code in either here or project guidence, that do something after a certain time has passed. Most, if not ALL have examples. Find them, read them, learn from them, and write your own. Come back when you have an actual code that compiles or at least has some errors that make sense based on what you wrote.

No code, no help.

Sorry but i am not so experience as all the others here

It doesn't take experience to see what is on the LCD screen. Does anything at all go on the screen? Have you tried just sending the data to the serial monitor?

I forgot to add a closing ) in the if statement.

Works with the exception mills()

???

Post your full code

Follow the trace on the circuit board back to GND or V-.

Code:

boolean latch = false;
unsigned long timer = 0;
byte LED_pin = 13;

void setup() {
.
.
.
}

void loop() {

//debounce code here

if(button == HIGH) {
latch = !latch;
timer = millis();

  if(latch == true && (millis() - timer < 3000) {
  digitalWrite(LED_pin, HIGH);
  }

  else {
  digitalWrite(LED_pin, LOW);
  }
 }
}

untested but if you fill in the rest, it should work.

Start with the examples and maybe even a forum search, there is plenty of codes in here to help you get started.

What made you put 255 in here as RX?

SoftwareSerial serLCD = SoftwareSerial(255, TxPin);

Yes, an actual chip. Or if you have a few transistors lying around, you can make your own H bridge. Look up H-Bridge IC

[arduino]

Have you tried a regular H-Bridge? Also you cannot have both USB and battery plugged into the arduino together.

I would assume the middle IS ground, but of all my years dealing with electronics and other situations, I've learned to NEVER assume.
Follow the traces on the circuit board, and see what pin goes to ground. It may or may not be the middle pin, you have to check.

The IR has two in one. The mouse detects which of the two gets blocked first, then decides on which direction it is going.

myInts[0] = '0' single quotes.

The first zero will drop out, leaving you with just 1, not 01.

You said you already made a map of the buttons.

Code:

if (page == 70 && p.y > 211 && p.y < 231 &&  p.x > 84 && p.x <104  ){ // im guessing button ZERO
      tft.setTextSize(3);
      tft.fillRect(82, 201, 25, 25, BLUE);
      tft.setCursor(82, 201);
      tft.println ("0");
      myInts[counter++] = '0'; // *** this is the setup needed *** the numbers must go between single quotes '  '
                               // Everytime you press a button, counter updates and the char is stored
                               // If special button is pressed, convert data in array.
    }
    else if  (page == 70 && p.y > 290 && p.y < 310 &&  p.x > 190 && p.x <215 && q==1){ // Button ONE
      tft.setTextSize(3);
      tft.fillRect(110, 201, 25, 25, BLUE);
      tft.setCursor(110, 201);
      tft.println ("1");
      myInts[counter++] = '1';
    }
    .  TWO
    .  THREE
    .  FOUR
  And so on

Added: You also need to make sure you set the counter back to zero after you convert the array to an int.

If he researched the atoi function, then he should know that it needs to be char null terminated. What I gave him was just an example to build on.

OP, your numbers must be chars, not actual ints. '1','2','3'... and so on.
