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.

Keep IC’s close toegether and imagine that it is a printed circtuit board layout. Best practice of using the breadboard is to use short solid wire leads and neatly connect flush to the board without large inductive loops.

Remember I said check power? Home Questions Tags Users Unanswered. Found this item with same quality anx at a lower price but prefer to buy from robokits. Thanks a lot for helping us to maintain competitive prices. 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.

ht12d & ht12e

Easy Interface with and RF or an Infrared transmission medium. I see you do not have jumpers to join each side of the power rails. This ICs are paired with each andd. Buy 15 or more pieces to get Free Shipping Option Availability: Guilherme Garcia da Rosa 2 3 7.

They are capable of Encoding 12 bit of information which consists of N address bits and N data bits.

Add decoupling caps close to the IC. I know but, and I’m going to sound like Olin here it should be easy to see how inconvenient it ajd, even for a new user. Full Name Email Address.

Please submit the url of the better price you saw. All is working now, thanks to all. TB Stepper Motor Driver 4. We will lauch an immediate investigation and try our best to beat the hg12e, if it proves to be the same product. Easy to Use, Versatile Robotics Kits Note there is a gap on both sides down the middle for the Blue and Red outer rails.


Email Required, but never shown. And the picture of the circuit done: Actual product may vary from the product photograph displayed above. Thanks for all your h12e, 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 Ht112d was making wrong, I left them all at 1 and changed the resistors in them both cause the TX need to anc 20 times the resistence of the receiver, in other words 50k and 1M resistors.

Mercury ball tilt switch 5mm dia. Sign up using Email and Password. Use staples for power and ground rails. Yah but Ht112e agree.
