Hi I have been playing with Arduinos for a little bit and want to extend my experience to building my own,
I have a project, basically an remote buzzer, using RF boards such as http://www.instructables.com/id/RF-315433-MHz-Transmitter-receiver-Module-and-Ardu/
on the tx, I want a small portable button, that a person can carry around and the battery should last a long time, like weeks,
on the rx, a simple buzzer when the TX button is pressed, the buzzer pin goes to HIGH, and when not pressed stays low..
Very simple logic and only need 2 I/O digital pins on both RX/TX
Where should I begin my research, and on what microcontroller chip? And hopefully I can transfer my knowledge of arduino to this project.
