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.

I’ve never tried this before but looks ok. 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. Keep IC’s close toegether and imagine that it is a printed circtuit board layout.
This ICs are paired with each other. I see you do not have jumpers to join each side of the power rails. Avoid long jumper wires at all costs. Tony EE rocketscientist ht1e 2 21 Try to get thin solid wire 24 AWG I believe. Actual product may vary from the product photograph displayed ht12s. Easy Interface with and RF or an Infrared transmission medium.

HT12E & HT12D ENCODER DECODER IC
Please submit the url of the better price you saw. 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 cause the TX need to have 20 times the resistence of the ht122d, in other words 50k and 1M resistors.
For fun here is a free tool to help design, layout and simulate. Thanks a lot for helping us to maintain competitive prices.
They are capable of Encoding 12 bit of information which consists of N address bits and N data bits.

RF Remote Based Dc Motor Driver Using HT12E & HT12D
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. Email Required, but never shown.
We will lauch an immediate investigation and try our best to beat the price, if it proves to be the same product. Be the first to write a review. Note there is a gap on both sides down the middle for the Blue and Red outer rails.
