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.

All is working now, thanks to all. That means you need an inexpensive multimeter to do this. 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.
Easy Interface with and RF or an Infrared transmission medium. Return hh12d Refund Policy. Tony EE rocketscientist 62k 2 21 Customers who bought this product also purchased Keep IC’s close toegether and imagine that it is a printed circtuit board layout. This ICs are paired with each other.
Thanks for all your awnser, after studying a little bit jt12d 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 ht12 receiver, in other words 50k and 1M resistors.

We will lauch an immediate investigation and try our best to beat the price, if it proves to be the same product. Sign up using Email and Password. Full Name Email Address.

HT12E & HT12D ENCODER DECODER IC
Remember I said check power? I’ve never tried this before but looks ok.
Be the first to write a review. Avoid long jumper wires at all costs. They are capable of Encoding 12 bit of information which consists of N address bits and N data bits. Thanks a lot for helping us to maintain competitive annd. I’m working on a similar circuit. Try to get thin solid wire 24 AWG I believe.
Use staples for power and ground rails. Email Required, but never shown.
And the picture of the circuit done: Home Questions Tags Users Unanswered. Note there is a gap on both sides down the middle for the Blue and Red outer rails. I see you do not have jumpers to join each side of the power rails. We will notify you the result by email. TB Stepper Motor Driver 4. Please submit the url of the better price you saw.
Did you really need to post that many images without the full URLS, no less? Guilherme Garcia da Rosa 2 3 7. So, you an saying, when you grounded all the pins on the left of HT12D and 12E, it worked?
