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.

They are capable of Encoding 12 bit of information which consists of N address bits and N data bits. I see you do not have jumpers to join ht12r side of the power rails. Remember I said check power?
Sign up using Facebook. Found this item with same quality and at a lower price but prefer to buy from robokits. Email Required, but never shown. This ICs are paired with each other. Tony EE rocketscientist 62k 2 21 So, you are saying, when you grounded all the pins on the left of HT12D and 12E, it worked?
Home Questions Tags Users Unanswered. Avoid long jumper wires at all costs. Buy 15 or more yt12e to get Free Shipping Option Availability: Thanks a lot for helping anr to maintain competitive prices. Mercury ball tilt switch 5mm dia. That means you need an inexpensive multimeter to do this. Note there is a gap on both sides down the middle for the Blue and Red outer rails.
All is working now, thanks to all. Photograph just for reference. 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. Best practice of using the breadboard is to ht1e short solid wire leads and neatly connect flush to the board without large inductive loops.
Keep IC’s close toegether and imagine that it is a printed circtuit board nad.

We will lauch an immediate investigation and try our best to beat the price, if it proves to be the same product. Use staples for power and ground rails.
Yah but I agree. Guilherme Garcia da Rosa 2 3 7. Post as a guest Name. For fun here is a free tool to help design, layout and simulate.
Actual product may vary from the product photograph displayed above. Be the first to write a review. 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 jt12d 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 receiver, in other words 50k and 1M resistors.
I know but, and I’m going to sound like Olin here it should be easy to see how inconvenient it is, even for a new user. Jt12d working on a similar circuit.
RF Remote Based Dc Motor Driver Using HT12E & HT12D
Try to get thin solid wire 24 AWG I believe. Add decoupling caps close to the IC.
Easy to Use, Versatile Hg12e Kits Please submit the url of the better price you saw. Don’t use wire with thick insulation. Did you really need to post that many images without the full URLS, no less? And the picture of the circuit done:
