Multiple Sensors and LED Drivers?

Hi,

I'm newbie to these Electronic things.
I want to ask:
Is it possible to connect 25 PIR sensors and and 6 TLC5940 Led driver into 1 Arduino Uno?

I need to control 25 independent RGB LEDs by 25 PIR sensors in order to create a "Touch table".

Here are the PIR Sensor datasheets:

Thanks alot.

your going in the wrong direction you cant interface PIR's to make a touch table ! they will give you false readings ! look into some other options

Do you have any suggest?:slight_smile:

That is very cool looking. I think the coding and interfacing to an Arduino would be a piece of cake. The 'hard part' is building the light modules and the touch sensors for the first row. And sound effects could get.....complex. :wink:

Keep us posted, It could be something I would build someday for the grand kids.
