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.

Note there is a gap on both sides down the middle for the Blue and Red outer rails. I wondered whether these processors were still available – they are! So, you are saying, when you grounded all the pins on the left of HT12D and 12E, it worked? Post as a guest Name. HT12E Encoder circuit The basic circuit arrangements for the encoder: 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.

It would be possible to control literally hundreds of external devices this way. Home Questions Tags Users Unanswered. Easy Interface with and RF or an Infrared transmission medium. All is working now, thanks to all. Photograph just for reference. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

RF Remote Based Dc Motor Driver Using HT12E & HT12D

Remember I said check power? Number 99 entered quits the script. Sign up using Email and Password. I’ve never tried this before but looks ok. Add decoupling caps close to the IC. Be the first to write a review. The encoder HT12E is capable of encoding information comprising 12 bits in total; 8 address bits and 4 data bits. Hh12d 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.


Email Required, but never nt12d.

I’m working on a similar circuit. Return and Refund Policy. Full Name Email Address.

Newer Post Older Post Home. 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. Found this item with same quality and at a lower price but prefer to buy from robokits. I see you do not have jumpers to join each side of the power rails. We will notify you the result by email.

Try to get thin solid wire 24 AWG I believe. Actual product may vary from the product photograph displayed above. By clicking “Post Your Answer”, you acknowledge that you have read our updated h1t2e of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

I also thought it would be a great opportunity to fully investigate the operation of the two processors to help me better understand how I might use these in the future.

We will lauch an immediate investigation and try our best to beat the price, if it proves to be the same product. 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 with other potential uses. I have included a ht1e2 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.



Easy to Use, Versatile Robotics Kits For fun here is a free tool to help design, layout and simulate. 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.

Did you really need to post that th12d images without the full URLS, no less?

Don’t use wire with thick insulation. The transmission of the data stream can be over an RF link or direct connection using 2-core cable. Use staples for power and ground rails.

Guilherme Garcia da Rosa 2 3 7.

Best practice of using the breadboard is to use short solid wire leads and neatly connect flush to the board without large inductive loops. This ICs are paired with each other. Buy 15 or more pieces to get Free Shipping Option Availability: Tony EE rocketscientist 62k 2 21 Customers who bought this product also purchased Using the Raspberry Pi to control.

I haven’t drawn any circuits for this as the interfacing is straight forward as both the Raspberry Pi and the HT12E operate at 3. That means you need an inexpensive multimeter to do this. Sign up using Facebook.

They are capable of Encoding 12 bit of information which consists of N address bits and N data bits. The outputs from the HT12D decoder can be used to switch connected logic circuitry or other attached devices via suitable interfaces.
