Up count and reset to zero

Hi I am having a problem in modifying a program to reset a up-counter to zero.

I am using a Uno and a 16x2 Lcd to count a pulse input. When input pulse stops I want to be able to reset the count back to zero by using a push button switch.

The program I am using has 2 switches one for up counting and the other for down counting.

I am only using the up count switch sw1 in the code and I have added count++; to increase the increment the count by 2 each time the sw1 is activated.

I would like to use sw2 as the means to reset

Have tried various methods but no success.

// test for upp
#include <LiquidCrystal.h>
// swtich 1 connected at Pin 8 and other end to GND
// switch 2 connected at Pin 9 and other end to GND
// Refer Circuit

int sw1 = 8;  // Connect pin 8 to SW1
int sw2 = 9;  // Connect pin 9 to SW2
int count = 0;
#include <LiquidCrystal.h>
// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(7, 6, 5, 4, 3, 2);

void setup()
{
  // set up the LCD's number of columns and rows:
  lcd.begin(16, 2);
  // Print a message to the LCD.
  lcd.print("SHAW COUNTER");
  // Declare Switches as INPUT to Arduino
  pinMode(sw1, INPUT);
  pinMode(sw2, INPUT);
  digitalWrite(sw1, HIGH);
  digitalWrite(sw2, HIGH);
}

void loop()
{
  if (digitalRead(sw1) == LOW)  // if SW1 is pressed perform action described in loop
  {
    count++;                    // Increment Count by 1
    count++;                    // added this and gives Increment of 2 which is required 
    lcd.setCursor(0, 1);
    lcd.print(count);
    delay(400);
  }
  if (digitalRead(sw2) == LOW)   // if SW2 is pressed perform action described in loop
  {
    count--;                     // Decrement Count by 1
       if (count < 0)
      count = 0;
    lcd.setCursor(0, 1);
    lcd.print(count);
    delay(400);
  }

}

Any help would be appreciated
Thanks

I have added count++; to increase the increment the count by 2 each time the sw1 is activated.

That is not what the code does. The code increments count twice whilst the switch is pressed, not when it becomes pressed. The delay() slows down the incrementing but it would be better if you did it correctly. Look at the StateChangeDetection example in the IDE.

Also, change

count++
count++;

to

count = count + 2;

or

count +=2;

to tidy up the code

Have tried various methods but no success.

Post what you tried. What went wrong ?
