Arduino+pir sensor+sender to receiver+LED? Answered

I want to make something that alarms me when there is movement outside my door, with an arduino uno and pir sensor, and in my room I have another arduino uno with an LED that blinks when there is movement on the arduino outside. And i want the whole thing wireless.
How can I do that? and what is the arduino code for it? thanks.

Either that, or look around here especially in the "Related" column.

The wireless aspect will be the pricy part. I would use LAN with an ethernet shield. Knockoffs are readily available for 10 bucks a pop. Not wireless, but close. If you are really intent on going wireless look up the wifly shield.

Your Arduino can run the oscillator and interrupt on the NE555 output using software to decide if it a dog or adult. Additionally changing the Fq you can learn to figure the mass of what is outside your door.
