So basically I am very new to Arduino and Electronics in general, however I am a software programmer so that side of things does not faze me.
However, I would like to build a basic setup where a beam is tripped, then a second beam is tripped further away. From my research this seems very straight forward in smaller applications, indoors etc however I need this to do something a bit more.
The situation is that this will be used outside with varying amounts of sunlight (based on weather) and possibly rain also.
So I need to know if there is a sensor that can be used with an Arduino board that would suit this situation? As I said I am new to all of this so scrolling through pages of maplin sensors just confuses me as I am not sure what I need, not sure of range, not sure of what type or sensor I need, power supply, etc etc.
Any hand to hold will be appreciated!
The theory is that a beam will be broken and a timer started, then when the second beam is broken then the timer will stop and result will be displayed.
What I need is advice on sensors / emiiters required to achieve this considering its application. They will need to be at least 10 meters apart and used outside.
