(Its my first project with arduinos, so i dont know much about it.)
Working on a project with an Arduino Duemilanove and a Arduino mini light.
The idea is to make a signal between the two Arduinos with a reciver and an transmitter (an rf link kit like: http://www.elechouse.com/elechouse/images/product/433Mhz%20RF%20Link%20Kit.jpg)
We want to make a signal strength that would be like 2 meters. When this signal has been broken, due to the distance has ben expanted, our buzzer will start to beep.
Since its the first time ive programmed an arduino, it all looks like a jungel. Can someone give me a hint about what codes i might want to use?
