My sketch below is simply using a touch sensor to activate a servo motor to go from from initial position 0 to 180 then back to 0. then I want the Adruino NANO to go to sleep to conserve some battery life.
Being a novice to programing and after many attempts to use his code and intergrade it with mine. Was unsuccessful.
so if anyone can help intergrade the gammon's sketch below into mine it would be greatly appreciated. As I'm out of ideas.
HERE IS MY SKETCH
#include <Servo.h>
// constants won't change
const int SENSOR = 2; // Arduino pin connected to motion sensor's pin 7
const int SERVO = 9; // Arduino pin connected to servo motor's pin 9
Servo servo; // create servo object to control a servo
int pos = 0; // variable to store the servo position
// variables will change:
int lastMotionState; // the previous state of motion sensor
int currentMotionState; // the current state of motion sensor
void setup() {
Serial.begin(9600); // initialize serial
pinMode(SENSOR, INPUT); // set arduino pin 9 to input mode
servo.attach(SERVO); // attaches the servo on pin 12 to the servo object
servo.write(0);
currentMotionState = digitalRead(SENSOR);
}
void loop() {
lastMotionState = currentMotionState; // save the last state
currentMotionState = digitalRead(SENSOR); // read new state
if (currentMotionState == LOW && lastMotionState == HIGH) { // pin state change: LOW -> HIGH
Serial.println("OFF");
servo.write(0);
delay(100); // waits (X)ms for the servo to reach the position
}
else
if (currentMotionState == HIGH && lastMotionState == LOW) { // pin state change: HIGH -> LOW
Serial.println("ACTIVE");
servo.write(180);
delay(2000); // waits (x)ms for the servo to reach the position
}
delay(10); // repeats program - larger delay - trigger is
}

This sketch is part of the beginners guide to putting your Arduino to sleep tutorial. It is to demonstrate how to put your arduino into deep sleep and how to wake it up.
*/
#include <avr/sleep.h>//this AVR library contains the methods that controls the sleep modes
#define interruptPin 2 //Pin we are going to use to wake up the Arduino
void setup() {
Serial.begin(115200);//Start Serial Comunication
pinMode(LED_BUILTIN,OUTPUT);//We use the led on pin 13 to indecate when Arduino is A sleep
pinMode(interruptPin,INPUT_PULLUP);//Set pin d2 to input using the buildin pullup resistor
digitalWrite(LED_BUILTIN,HIGH);//turning LED on
}
void loop() {
delay(5000);//wait 5 seconds before going to sleep
Going_To_Sleep();
}
void Going_To_Sleep(){
sleep_enable();//Enabling sleep mode
attachInterrupt(0, wakeUp, LOW);//attaching a interrupt to pin d2
set_sleep_mode(SLEEP_MODE_PWR_DOWN);//Setting the sleep mode, in our case full sleep
digitalWrite(LED_BUILTIN,LOW);//turning LED off
delay(1000); //wait a second to allow the led to be turned off before going to sleep
sleep_cpu();//activating sleep mode
Serial.println("just woke up!");//next line of code executed after the interrupt
digitalWrite(LED_BUILTIN,HIGH);//turning LED on
}
void wakeUp(){
Serial.println("Interrrupt Fired");//Print message to serial monitor
sleep_disable();//Disable sleep mode
detachInterrupt(0); //Removes the interrupt from pin 2;
}
