Arduino switch not working

the_kushima_arduino_rf · September 19, 2022, 7:50am

Hello I have a problem I use a ic2 lcd and ultrasonic sensor but it malfunctions

Here's problem

I need the button(its a switch like button with two terminals not a 4 terminal tactile button) to display something but its just does it without a button press

Important points
The switch button is connected with out a resistor

#include <hd44780.h>

#include <Wire.h> 
#include <hd44780ioClass/hd44780_I2Cexp.h>
#include <ezButton.h>



//turn on an LED based on distance measured by
  //ultrasonic sensor

    


  
  int pinled=9;
  const  int trigger=6;
  const  int echo=7;
  float  distance;
  float dist_inches;
  ezButton toggleSwitch(5);  

    hd44780_I2Cexp lcd;
  
  void setup()
{  Serial.begin(9600);
    pinMode(trigger,OUTPUT);
    pinMode(echo,INPUT);
    pinMode(pinled,OUTPUT);
    toggleSwitch.setDebounceTime(50); // set debounce time to 50 milliseconds
    lcd.init();
    lcd.backlight();
    lcd.setCursor(0,0);
    lcd.print("hello user code");
    delay(9000);
    lcd.setCursor(0,0);
    lcd.print("LOADING JAVA>____");

PLEASE HELP ME!!!!!!!!!!!!

if you use if without braces, the condition only affects the one line immediately following the operator

PS I replaced "parenthesis" word to braces as @J-M-L mentioned

the_kushima_arduino_rf · September 19, 2022, 7:56am

SO WHAT SHOULD I DO I AM A VERY BIG NEWBIE
please help me

J-M-L · September 19, 2022, 8:30am

like you did with other if() in the code ➜ use braces (not parentheses) {} to group together what belongs to the if clause

if (condition) {
  // code if condition is true
  ...
} else {
 // code if condition is false
  ...
}

Use the language reference to get correct syntax

b707 · September 19, 2022, 9:19am

read the manual

When you use any button libraries, please do not use delay() function. It will block operation of button libraries

docdoc · September 20, 2022, 7:55am

That's the very last problem on that code...

JCA34F · September 20, 2022, 8:06am

How is the button wired? Do you have a pullup or pulldown resistor connected to pin 5?
