remote control for presentation slides

[uzairsukhera]

how can we make a remote controll for the power point presentations to move to next page. I want to use micro-controller to make an infrared reciever device which can be connected to PC through usb port. the remte control will be IRDA transmittor with a few buttons. How can the interfacing of the reciever with the PC done? and how can the PC respond to the up/down commands transmitted to it through the usb pot from the reciever?

Hi,

You can buy a device like this. It is called an rf or wireless mouse. They make one with a pretty good range and an internal gyro that detects your hand movements.

Should you like to make your own or just like building things. Think about it this way. Take an existing USB mouse and then write some microcontroller code to electrically close the mouse buttons. Then get an IR receiver and write additional code to decode the IR stream into the appropriate mouse keys. You could even write special macros associated with various IR remote keys. The beauty is that the PC end is already done as the mouse driver takes care of that.
IR decode algorithms are on several web sites.

"banjo" gave u the best, easiest, cheapest solution.
using a mouse will help u too much, cz u won't interface with the pc.
ur interface is going to be with the mouse

you want to design the project from scratch YOURSELF?
or just you want to get such a device?

I think he want to redo the project himself. So if anyone has a schematic or block diagram, it will be really helpful.
