I'm planning on creating a gesture recognition system. I imagine that I have to drive four IR emitters but not sure what technique to use. Please suggest what should I do in this case and thank you in advance.

 

You aren't giving very much information to work with. What is it you plan to use these four IR emitters for? What kind of signal are you expecting to get and work with? What kind of environment is your system going to be operating in?

 

You drive it like you drive an LED (assuming it is an LED IR emitter.)

Do you have circuit or block diagram?

 

How many years of experience do you have in this field?
