rf ac motor control with 8051

[khushi]

Hello,
To A.M.bhatt,

As u uploaded the circuit for ac motor control using rf,
I have build that circuit but not working.
I want to use this circuit for my home.

What is going wrong I m not able to find whether coding or circuit.

Please help me sir

check first if transmitter works fine?

then check receiver section HT12D.

if they both are working correctly

then check for micro controller section.

and finaly check your AC motor driver section

there may be problem at any place

sir

i have checked all connection and that r ok.

Tx Rx both working fine as i pressed the key from tx side, receiver led blink like chattering.

ZCD o/p connected to intrrupt 1 P3.3

HT12d 17 no pin is connected to P3.2

I m not geeting the triac pulse from microcontroller port 2^2.

i think so there is some mistake going in to the code.

Please help me

the pulse output is from pin P2.0 not p2.2

Ya i know but i have configured on Port P2.2.
