I am interfacing PIC32 MCU with 24 inputs and UART. When any inputs comes, this data is transferred to PC via uart. I am using multiple if condition like

if(input1==high)
{
  putsUART("input 1 ON\n");
}
if(input2==high)
{
  putsUART("input 2 ON\n");
}

What this if condition is doing is whenever an input comes, it keep on printing the data like

input 1 ON
input 1 ON
input 1 ON

and it goes on. I want it to be displayed once only. For example, if I applied input1, input 1 ON should be printed once and if remove the input input 1 OFF should be displayed once. I don't know how can I run this if condition only once. Please help. Thanks.!

CODE(just for 3 inputs):

 if(PORTAbits.RA6 == 0)         //INPUT 1
 {
   putsUART2("Input: 1 ON\n");
   Delayms(1000);
 }
 if(PORTAbits.RA7 == 0)          //INPUT 2
 {
   putsUART2("Input: 2 ON\n");
   Delayms(1000);
 }
 if(PORTAbits.RG13 == 0)          //INPUT 3
 {
   putsUART2("Input: 3 ON\n");
   Delayms(1000);
 }
