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.

RF Remote Based Dc Motor Driver Using HT12E & HT12D

I see you do not have jumpers to join each side of the power rails. Email Required, but never shown. Easy to Use, Versatile Robotics Kits All is working now, thanks to all. Sign up using Facebook. Found this item with same h12e and at a lower price but prefer to buy from robokits.

Please submit the url of the better price you saw.

This ICs are paired with each other. I’m working on a similar circuit. That means you need an inexpensive multimeter to do this. Add decoupling caps close to the IC. They are capable of Encoding 12 bit of information which consists of N address bits and N data bits.

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 ht12f 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.

Customers who bought this product also purchased We will lauch an immediate investigation and try our best to beat the price, if it proves to be the same product.

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. Easy Interface with and RF or an Infrared transmission medium. Guilherme Garcia da Rosa 2 3 7.


The Decoder receive the serial address and data from its corresponding decoder, transmitted by a hh12d using an RF transmission medium and gives output to the output pins after processing the ht1e. Don’t use wire with thick insulation. And the picture of the circuit done: Return and Refund Policy. Best practice of using the breadboard is to use short solid wire leads and neatly connect flush to the board without large inductive loops.

Actual product may vary from the product photograph displayed above. Yah but I agree.
