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.

I’ve never tried this before but looks ok. Please submit the url of the better price you saw. For fun here is a free tool to help design, layout and simulate.

I know but, th12e I’m going to sound like Olin here it should be easy to see how inconvenient it is, even for a new user. TB Stepper Motor Driver 4.

We will notify you the result by email. Return and Refund Policy. Use staples for power and ground rails. That means you need an inexpensive multimeter to do this. Easy to Use, Versatile Robotics Kits Guilherme Garcia da Rosa 2 3 7. Yah but I agree.

This ICs are paired with each other.

Mercury ball tilt switch 5mm dia. I’m working on a similar circuit. 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 ht12f 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 in them hy12d cause the TX need to have 20 times the resistence of the receiver, in other words 50k and 1M resistors.

All is working now, thanks to all. Tony EE rocketscientist 62k 2 21 Actual product may vary hr12d the product photograph displayed above.

RF Remote Based Dc Motor Driver Using HT12E & HT12D

Buy 15 or more pieces to get Free Anf 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. Add decoupling caps close to the IC. Keep IC’s close toegether and imagine that it is a printed circtuit board layout.
