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.

Note there is a gap on both sides down the middle for the Blue and Red outer rails.

And the picture of the circuit hf12d I’m working on a similar circuit. TB Stepper Motor Driver 4. This ICs are paired with each other. Sign up using Facebook. Email Required, but never shown. So, you are saying, when you grounded all the pins on the left of HT12D and 12E, it worked?
Try to get thin solid wire 24 AWG I believe. Buy 15 or more pieces to get Free Shipping Option Availability: Easy to Use, Versatile Robotics Kits Keep IC’s close toegether and imagine that it is a printed ht122e board layout.
HT12E & HT12D ENCODER DECODER IC
We will lauch an immediate investigation and try our best to beat the price, if it proves to be the same product.
Avoid long jumper wires at all costs. Found this item with same quality and at a lower price but prefer to buy from robokits. We will notify you the result by email. Thanks a lot yt12d helping us to maintain competitive prices.
Use staples for power and ground rails. All is working now, thanks to all. Yah but I agree. Best practice of using the breadboard is to use short solid wire leads and neatly connect flush to the board without large inductive loops.
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. Guilherme Garcia da Rosa 2 3 7. Easy Interface with and RF or an Infrared transmission medium.

Mercury ball tilt switch 5mm dia. 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 h12d changed the resistors in them both cause the TX need to have 20 times the resistence of the receiver, in other words 50k and 1M resistors.
I’ve never tried this before but looks ok. Sign up or log in Sign up using Google. For fun here is a free tool to help design, layout and simulate.
