12 Channel Relay + 2 Channel Dimmer control by IR Remote and keyboard

12 Channel Relay + 2 Channel Dimmer control by IR Remote and keyboard
as extension to IR(infrared) Remote Control Relay Board with PIC 12F675 Microcontroller i have done this quite a useful project after too many requests. by using this hardware user have option to turn up to 12 relay on and off and two loads (like fan or motor) can be controlled with adjustable speed in case of motor , or adjustable intensity in case of a bulb.

this project is directly involved with high voltage AC which may cause sever damage. proceed with caution.
i will not be responsible for any risk involved,  you are on you own.

IR protocol 

IR protocol is same as previous projects . we use NEC protocol please refer to this link to know more about NEC protocol

Hardware

Schematic
the main PCB contains all the components  except dimmer triac , they are mounted on separate removable module kind of pcb which can be inserted either one of them , both of them or none of them as per requirements if dimmer functionality is required.
as parts availability was primary concern so whole schematic is designed around very basic components , the system is built around only one microcontroller PIC16F877A which is quite cheap in terms of cost and performance. but as this part is available in most part of the world easily it is a good choice.
there are total 12+2 switch button on the main board. 12 switches can be used to turn any relay on and off and other 2 switches are used to control dimmers from 0 (off) to level 5(max) each time you press associated button dimmer will increase one step to max.
all the relay and both of the dimmers can be controlled by the NEC protocol based remote.

Software 
whole source is written in c , with
HI-TECH C Compiler for PIC10/12/16 MCUs  V9.83
all the latest source files, PCB gerber, Schematic PDF are available on github.    or you can download from this direct link (may not be latest) .
