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.

ElectronicAdventures: Data Encoder/Decoder HT12E/HT12D

Trigger send trigger pulse. Avoid long jumper wires at all costs. Sign up using Email and Password.

Remember I said check power? It could be said that this is a very convoluted way to use this technology but it was really useful to experiment and prove that it was possible. Pabitha Pabi 25 June at The outputs from the HT12D decoder can be used to switch connected logic circuitry or other attached devices via suitable interfaces. Found this item with same quality and at a lower price but prefer to buy from gt12e. For fun here is a free tool hht12e help design, layout and simulate.

We will lauch an immediate investigation and try our best to beat the price, if it proves to be the same product. Thanks a lot for helping us to maintain competitive prices. Keep IC’s close toegether and imagine that it is a printed circtuit board layout.

And the picture of the circuit done: All is working now, thanks to all.

HT12E, HT12D RF board

ClearAll set A ports to ”. The output from the encoder can be used in various ways; for example to feed a Radio Frequency or infrared transmitteror it could be directly connected to a decoding processor. Post as a guest Name. Email Required, but never shown. Add decoupling caps close to the IC.

So, you are saying, when you grounded all the pins on the bt12e of HT12D and 12E, it worked? Don’t use wire with thick insulation.

With the possibilities of using multiple decoders HT12D all ‘listening’ on their individually configured addresses it is possible for the Raspberry Pi or Arduino to control both the address values and control the use of the data pins.

RF Remote Based Dc Motor Driver Using HT12E & HT12D

Return and Refund Policy. I have referenced this before in an earlier blog and the direct link is: Sign up using Facebook.


I’m working on a similar circuit. Easy to Use, Versatile Robotics Kits Yah but I agree. Home Questions Tags Users Unanswered. Using the Raspberry Pi to control. I’ve never tried this before but looks ok. This ICs are paired with each other.

Actual product may vary from the product photograph displayed above. Please submit the url of the better price you saw. Be the first to write a review. I have included a simple Python3 script below, which prompts the user to enter a number between 0 and 15, and using Binary Coded Decimal, sets the AD8 – AD11 pins to convey the user entered number correctly.

I began to think about how I could use this technology with the current range of micro-controllers such as the Arduino and the Raspberry Pi, together hy12e other potential uses. 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 each side of the power rails. Note there is a gap on both sides down the middle for the Blue and Red outer rails.
