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 ?
#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
int pirSensor = 0;
int THRESHOLD = 149;
byte val = 0;
tmrpcm.speakerPin = 9; //11 on Mega, 9 on Uno, Nano, etc
tmrpcm.play("1.wav"); //plays a file everytime uno resets
mychar = Serial.read();
val = analogRead(pirSensor);
if (val >= THRESHOLD)
pls help me.
