Hy, I want to add to my amplifier an motorized volume potentiometer controlled by a remote control.

I like the idea but i can't find any schematics
If someone knows resources for this post here

Adrian,

 

hi,
Have you considered 'digitally controlled' potentiometers?

No i don't want a digital pot, i want it to be analog with a big aluminium know and to be controlled by a remote control, just like ESP project110, nice circuit but i don't have the pic source code

 

Either write your own PIC code (you can 'steal' suitable code from my tutorials), or use the Holtek remote control chips.

I'm not good in programming PIC microcontrollers, so just want another schematic resources if they are

 

Like I said above, try the Holtek chips then, have a look at

You did not understand me, i don't have enough experience to design o full project based on holtek chip, I just want a schematic or a project DIY (including HEX) like ESP Project 110 or Silicon Chip Remote Volume Control For Stereo Amplifiers, the only problem is that i don't have the HEX file for PIC because those are commercial products

 

Buy the article from Silicon Chip, that way you get the .hex file. You'll still have to program the 16F84.

if you check the download section the assembly,hex and pcb are there.

 

Ya, you're right
