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.

Customers who bought this product also purchased And the picture of the circuit done: All is working now, thanks to all. Home Questions Tags Users Unanswered. They are capable of Encoding 12 bit of information which consists of N address bits and N data bits.
Best practice of using the breadboard is to use ajd solid wire leads and neatly connect flush to the board without large inductive loops. TB Stepper Motor Driver 4.
Try to get thin solid wire 24 AWG I believe. 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. I’m working on a similar circuit. We will notify you the result by email. Post as a guest Name.

Did you really need to post that many images without the full URLS, no less? Note there is a gap on both sides down the middle for the Blue and Red outer rails. Mercury ball tilt switch 5mm dia. I see you do not have jumpers to join each side of the power rails.
RF Remote Based Dc Motor Driver Using HT12E & HT12D
Use staples for power and ground rails. Easy Interface with and RF or an Infrared transmission medium. Found this item with same quality and at a lower price but prefer to buy from robokits.
Avoid long jumper wires at all costs. Keep IC’s close toegether and imagine that it is a printed ht12 board layout. We will lauch an immediate investigation and try our best to beat the price, if it proves to be the same product.
ht12d & ht12e
I’ve never tried this before but looks ok. Guilherme Garcia da Rosa 2 3 7.
Actual product may vary from the product photograph displayed above. Buy 15 or more pieces to get Free Shipping Option Availability: 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 receiver, in other words 50k ht112d 1M resistors.
For fun here is a free tool to help design, layout and simulate. This ICs are paired with each other. Tony EE rocketscientist 62k 2 21 Sign up or log in Sign up using Google.
Yah but I agree. Email Required, but never shown. Be the first to write a review. Add decoupling caps close to the IC. Sign up using Email and Password. Thanks a lot for helping us to maintain competitive prices. So, you are saying, when you grounded all the pins on the left of HT12D and 12E, it worked?
