Connection of RF module to PIC16f877A

Above is connection of Rf to PIC microcontrollers via HD12E ic So in left side of ic A0-A7 these are address pins, you can ground all or put in any configuration according to your address. Right side of this ic contains data pins transmission enable pin oscillator pin and data out pin.
Between oscillator pin you have to connect 1.1Mohm resistance which acts as a RC oscillator AD8-AD11 are data pins which you have to connect with your PIC data pins. and last is te bar pin which you can connect to any  pic Pin it is used for TRansmission Enable.

Rest you can download all the data sheet and circuit connection from this link

note:- Connection for the RF receiver is same but you have to use HD12D IC
i hope it may help you all...

PIC PROGRAMMER (JDM)

Hello friends today i am going to tell u about how to make simple PIC programmer, of course u can buy it from market but it is very costly so its better to build it by ureself and the total cost will not be more than 100 rs.

So follow the Skematic below




now connection from icsp output to pic input follow this diagram:--




Final circuit will be something like below which we had made:-






NOTE U DONT HAVE TO CONNECT EXTERNAL POWER SUPPLY TO UR CIRCUIT OUTPUT FROM UR COMPUTER SERIAL PORT IS SUFFICIENT TO DRIVE UR CIRCUIT...


SOFTWARE USED FOR PROGRAMMING :-

WINPIC , PICPRO, JUST GOOGLE THESE NAMES U WILL SURELY GET DOWNLABLE LINK..IF NOT MAIL ME..

Module 1

This is module 1 consists of:-
1.LCD
2.EEPROM
3.RTC
4.KEYPAD
5.BUZZER
6.PIC MICROCONTROLLER

we had interfaced all components and the module is working fine but we need wireless module to transfer our data....
