Connecting LED to IR Reader

Hey,

I'm working on this project for university using arduino uno. I am trying to connect 30 LED lights to an IR receiver, I think i was meant to buy a IR sensor in order to create interaction between the LEDs and gesture right? if someone could help me out with this it would be great.

thanks!

Use a power shift register like a TPIC6B595, for 30 you will need to chain four together.

I don't know it is your project. What are you trying to do. Detecting gestures from a single detector is not going to happen. What sort of gestures?
