Please help , My UNO not detecting in Windows I tried in another PC but no success, i Think the FTDI chip firmware is lost so please give troubleshooting steps ..Thanks.

Ok Means I need A transformer to Downgrade ac to dc and then i need to monitor that DC supply and log it with sd card ? so please tell the workout for this , means how the workflow goes .. please thanks for giving your time .

Sorry to say but i didn't understand can you give me straight circuit for that ?
my need  is I have a analog PIR sensor that has 3 pins 1 for supply 5v one for signal out and rest is ground so i need that signal to convert to Digital to state ON or OFF pls help me and sorry if I missed something to say .

What values of resistance and cap is needed pls tell.

As I am not good in electronics can you please suggesta circuit example for me please?

Thanks , How to create a State High or Low using Analogue PIR sensor ?

Means i am talking about following code , in that i need only two states its high or low how to achieve this ?

Code:
#include <SD.h>                      // need to include the SD library
#include <TMRpcm.h>           //  also need to include this
#define SD_ChipSelectPin 10  //using digital pin 10 as chipselect on arduino UNO


     TMRpcm tmrpcm;   // create an object for use in this sketch
     char mychar;
     int pirSensor = 0;
     int THRESHOLD = 149;
     byte val = 0;
 
 void setup(){
     
     tmrpcm.speakerPin = 9; //11 on Mega, 9 on Uno, Nano, etc
     Serial.begin(9600);
     if (!SD.begin(SD_ChipSelectPin))
     {       
     Serial.println("SD fail");
     return;
     }
        tmrpcm.play("1.wav");     //plays a file everytime uno resets
     }
 void loop(){
 
     if(Serial.available()){ 
     mychar = Serial.read();
   
     val = analogRead(pirSensor);
     if (val >= THRESHOLD)
     {
     tmrpcm.play("1.wav");
     }
    }
  }


pls help me.
