Motion Control

Need some's help Thanks

in the code I want to add
if the motion is detecde again within 40 sec HIGH pin 12
if the motion is detected again after 70 sec HIGH pin 8

second sensor
motion detected by second motion sensor
&
if the motion is detecde two times within a min HIGH pin 7
if the motion is detected four times HIGH pin 8

MY CODE

int ledPin = 13; // LED pin
int motionPinfront = 2; // motion detector input pin
int motionPinrear = 3; // motion detector input pin
int senseMotion = 0; // variable to hold current state of motion detector
int timer = 500;

void setup() {
Serial.begin (9600);

pinMode(ledPin, OUTPUT);
pinMode(motionPinfront, INPUT);
pinMode(motionPinrear, INPUT);
delay (2000);
}

void loop()
{

senseMotion = digitalRead(motionPinfront);
if (senseMotion == HIGH)
{
blinky();
}
delay (timer);
Serial.println (senseMotion);
delay (10);
}

if
{

senseMotion = digitalRead(motionPinrear);
if (senseMotion == HIGH)
{
blinky();
}
delay (timer);
Serial.println (senseMotion);
delay (10);

void blinky()
{
for(int i=0; i<3; i++)/blinks three times/
{
digitalWrite(13,HIGH);
delay(200);
digitalWrite(13,LOW);
delay(200);
}
}

Your code does not compile - there is a closing brace early in loop that puts the code after it outside any function. Also, there is an if soon after with no condition to test. You might want to address those issues first and repost. When you do, please use the code tags '#' button on the toolbar to enclose it so it's more readable
