Hi,
This is only my third sketch.
Before this I only flashed leds and controlled a fan based on temp.
What I am doing is flashing a light three times and then leaving it on for a while then flashing it again.
That is the easy part.
It should only be on when it receives a signal on the Xbee. I have that part figured out.
What I am having trouble with is inserting an interrupt to shut the light off if I stop receiving signal from my xbee.
Should I be looking at something other than interrupts? Timers maybe?
I won't bore you with my failed interrupt attempts.
This is my code before I try to add an interrupt.
I Have to wait till it goes through the loop before it will stop.
That is fine for flashing but not for longer delays at the end.
If someone could edit it for me that would be great.
I am also open to any suggestions or opportunities learn.
Thanks for looking.
// spanker light control
// r1 = relay 1
// xbee pin 20 is connected to pin 7
int xbee = 7; // pin 7 input from xbee pin 20
int r1 = 2; // pin 2 output to relay 1 on shield
int val = 0; // variable to store the read value
void setup(){
pinMode (xbee, INPUT); // declare xbee as input
pinMode (r1, OUTPUT); // declare r1 as output
}
void loop(){
val = digitalRead(xbee); //read input pin
if (val == HIGH) {
digitalWrite(r1, HIGH); // turn light on
delay (500); // wait .5 seconds
digitalWrite(r1, LOW); // turn light off
delay (500); // wait .5 seconds
digitalWrite(r1, HIGH); // turn light on
delay (500); // wait .5 seconds
digitalWrite(r1, LOW); // turn light off
delay (500); // wait .5 seconds
digitalWrite(r1, HIGH); // turn light on
delay (90000); // wait 90 seconds
}
else {
digitalWrite (r1, LOW);
}
}
My project.
We have two fin spanking machines at work. I need to turn a light on when either of them are powered up.
I Have the Xbee hardware side working. I would just like for it to flash a few time when it comes on and then again every few minutes.
