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.

Be the first to write a review. Easy Interface with and RF or an Infrared transmission medium. Add decoupling caps close to the IC.
Note there is a gap on both sides down the middle znd the Blue and Red outer rails. 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. That means you need an inexpensive multimeter to do this.
This ICs are paired with each other. And the picture of the circuit done: Thanks for all your awnser, after studying a little bit into the RF module I found out my problem, the left side of both encoder and decoder are the Htt12d 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 the receiver, in other words 50k and 1M resistors.

Found this item with same quality and at a lower price but prefer to buy from robokits. Please submit the url of the better price you ht2d.
For fun here is a free tool to help design, layout and simulate. Mercury ball tilt switch 5mm dia. I’ve never tried this before but looks ok. We will lauch an immediate investigation and try our best to beat the price, if it proves to ad the same product. Post as a guest Name. 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.

All is working now, thanks to all. Try to get thin solid wire 24 AWG I believe.
