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. Yah but I agree.

And the picture of the circuit done: Add decoupling caps close to the IC. For fun here is a free tool nad help design, layout and simulate. Actual product may vary from the product photograph displayed above. I see you do not have jumpers to join each side of the power rails. Home Questions Tags Users Unanswered. They are capable of Encoding 12 bit of information which consists of N address bits and N data bits.

We will notify you the result by email. Thanks a lot for helping us to maintain competitive prices. So, you are saying, when you grounded all the pins on the left of HT12D and 12E, it worked?

Mercury ball tilt switch 5mm dia. This ICs are paired with each other. 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. All is working now, thanks to all. Guilherme Garcia da Rosa 2 3 7. Please submit the url ht12r the hr12d price you saw.

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

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 Address 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 annd them both cause the TX need to have 20 times the resistence of the receiver, in other words 50k and 1M resistors.

Remember I said check power?
