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.

I’m working on a similar circuit. Yah but I agree.
RF Remote Based Dc Motor Driver Using HT12E & HT12D
Don’t use wire with thick insulation. That means you need an inexpensive multimeter to do this. We will lauch an immediate investigation and try our best to beat the price, if it proves to be the same product. Mercury ball tilt switch 5mm dia. Use staples for power and ground rails. Sign up using Facebook.
I’ve never tried this before ht1d2 looks ok.
Email Required, but never shown. Guilherme Garcia da Rosa 2 3 7.
Try to get thin solid wire 24 AWG I believe. Found this item with same quality and at a lower price but prefer to buy from robokits. Return and Refund Policy. Thanks a lot for helping us to maintain competitive prices. We will notify you the result by email. Thanks for all your awnser, after studying a little bit into the RF module I found out my problem, anc left side of both encoder and decoder are the Address PIN, which means they will only communicate if ht122d addresses are the same, that ht12s 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 and 1M resistors.
Post as a guest Name. Buy 15 or more pieces to get Free Shipping Option Availability: 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.
Remember I said ht1d power?

Did you really need to post that many images without the full URLS, no less? Best practice of using the breadboard is to use short solid wire leads and neatly connect flush to the board without large inductive loops.
And the picture of the circuit done: This ICs are paired with each other. Sign up using Email and Password. Sign up or log in Sign up using Google. I see you do not have jumpers to join each side of the power rails. Avoid long jumper wires at all costs.
Please submit the url of the better price you saw. 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 to Use, Versatile Robotics Kits Note there is a gap on both sides down the middle for the Blue and Red outer ht12f. Tony EE rocketscientist 62k 2 21 Ht21e IC’s close toegether and imagine that it is a printed circtuit board layout.
Home Questions Tags Users Unanswered. So, you are saying, when you grounded all the pins on the left of HT12D and 12E, it worked? For fun here is a free tool to help design, layout and simulate. Actual product may vary from the product photograph displayed above.
