hey ..
I need help GUYS ..
I am using HT12E and HT12D for control home things with remote I have made circuit but I am not getting right frequency for IR transmitter….

In reply to shilpa yadav. use 1M resistor for HT12E and 47K/or 47K+3.3k resistors for HT 12D ., I am using this configuration and works well with RF modules.

And also, can it be used with an IR transmitter?

In reply to yousuff.

Open pin will read as HIGH (1)…
Refer the datasheet to find details about optimum osc resistance..
