Hi, Is there any way of receiving signal from photo-transister and others. If anyone know, please reply me with diagram how to hook it up to Arduino.

Thanks

What type of signal?

Hi, I mean, how to hook photo-transister or IR-transister to arduino

Same way you hook up an LED. You just need to pick the right current limiting resister from the power supply, the voltage drop across the IR LED, and the current the LED can tolerate.

To receive IR from remote controls? You need a $4 IR receiver module for 38KHz. Hopeless with a bare diode that lacks a bandpass filter for the carrier. Lots of examples of these designs - e.g., on AVRfreaks.net projects section. Probably an Arduino library for it too.
