r u doing a project on pid control, if so email me coz i am currently working on a pid project. we together can make something good:) give a brief intro of urself, like what u do and stuff. [email protected]

thank you for the kind reply. i am controlling the lamp using TRIAC phase angle control. secondly Integrator with propotional is a must to have a value at the ouput when the error goes to zero. the transducer used is a photovoltiac detector(solar cell). the controller will control any change in light intensity due to disturbances in the AC voltage supply and disturbances from any other light source. e.g doors and windows, light intensity usually flickers while watching tv due to light from tv. sometime in thunder storms when the windows are banging(open and close), in welding workshops these are all examples of some rapid disturbances, this will require a differentiator as well. this is all that i think maybe u have a better idea.

i need a pid controller practicle working circuit for light intensity control. plz help me out with this.

plz tell me some easily available ic, for transmitter and receiver which can be easily interfaced with 89c51

i am am working on a remote control project. can somebosy help me with the remote control circuit. i am using AT89C51 microcontroller. i need both the transmitter and receiver citcuits.
