Hi There,
I'm having some problems on a basic Encode/Decode circuit that i want to use as RF Remote.
It's based on the famous HT12E and HT12D IC as most people have used for this.
I'll be using it with RF Transmitter and Reciever based on Aurel's TX-SAW-MID 3V and RX-MID-3V.
But for testing things out i just builded the thing on basic blocks using only one switch and driving only one Led on the Receiver side and a wire from the DATA IN/OUT.
And while this one works no prob when using same PSU, it doesn't when separating these and having separate PSU's (still using Wire to connect Data IN/OUT, and same adress etc...)
And obviously doesn't wrok neither when using the RF TX/RX modules...
Attached is the Simple Schematic of it all, maybe i'm missing something, but i don't get why i don't have it when all driven with same PSU...
Thanks for any clarifications.
