HT12D AND HT12E PDF

This project has been design around HT12E and HT12D encoder / decoder chips from Holtek. With jumper selectable address on the receiver. The HT12E Encoder ICs are series of CMOS LSIs for Remote Control system applications. They are capable of Encoding 12 bit of information which consists of 8. Robokits India HT12E & HT12D Encoder and Decoder IC for RF Modules [RKI- ] – The HT 12E Encoder ICs are series of CMOS LSIs for Remote Control.

Add decoupling caps close to the IC. Note there is a gap on both sides down the middle for the Blue and Red outer rails.

Best practice of using the breadboard is to use short solid wire leads and neatly connect flush to the board without large inductive loops. TB Stepper Motor Driver 4.

That means you need an inexpensive multimeter to do this. The Decoder receive the serial address and data from its corresponding decoder, transmitted by a carrier using an RF transmission medium and gives output to the output pins after processing the data.

Thanks for all your awnser, after studying a little bit into the RF module I found out my problem, the left side of both encoder and decoder are the Address PIN, which means they will only communicate if those addresses are the same, that was what I was making wrong, I left them all at 1 and changed the resistors in them both bt12e the TX need to have hht12e times the resistence of the receiver, in other words 50k and 1M resistors.
