Choosing Battery for Robots. HT12D is a decoder integrated circuit that belongs to 2 12 series of decoders.

Connected to the Ground of circuit. The 4-bit data that is received can be obtained on pins AD0 to AD1 and an address of 8-bit has to be set using the pins A0 to A7. Skip to main content. TB Stepper Motor Driver 4. Interface SD Card with Arduino. This series of decoders are mainly used for remote control system applications, like decodrr alarm, car door controller, security system etc. Mercury ball tilt switch 5mm dia.

It is not mandatory to use it. The IC has a built in oscillator. Thanks a lot for helping us to maintain competitive prices. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. In simple terms, HT12D converts the serial input into parallel outputs. Be the first to write a review.

We will lauch an immediate investigation and try our best to beat the price, if it proves to be the same product.


The Encoded 12 bit output data obtained from HT12E has to be given here. They can also be connected to LED to physically view the received data.

These two ICs together form an Encoder and Decoder pair. This high-density System-in-Package SiP integrates controller, power switches, and support components. These are the 8-bit address bits, which is used to protect your data.

The IC is should be powered by 5V pin 18 and the ground pin pin 9 is grounded. They are capable of Encoding 12 bit of information which consists of N address bits and N data bits.

The input data code is decoded when no error or unmatched codes are found. Supply voltage; 5V 2. What is Web Browser. Virgin Galactic — Commercial Space Flight. It is very important that your Decoder should have the same address of that of the encoder. Easy to Use, Versatile Robotics Kits For decoding a data the IC will requires an oscillatorluckily this IC has one in-built.

The data on 4 bit latch type output pins remain unchanged until new is received. A valid transmission in indicated by a high signal at VT pin. Full Name Email Address.

Return and Refund Policy. A basic circuit diagram for the HT12D IC is shown below In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. Submitted by decoxer on 27 October If any valid data is received they can be obtained from these four pins. TL — Programmable Reference Voltage.

They are paired with 2 12 series of encoders. In the above circuit I dwcoder set the 8-bit address data as 0b, by connecting all address pins to ground. Photograph just for reference.


It is mainly provided to interface RF and infrared circuits. Easy Interface with and RF or an Infrared transmission medium.


This oscillator can be used by connecting these two pins through a 1M Resistor. Please submit the url of the better price you saw. This pin powers the IC should use only 5V. Found this item with same quality and at a lower price but prefer to buy from robokits. Buy 15 or more pieces to get Free Shipping Option Availability: Valid transmission; active high.

The Decoder receive the serial address and data from its corresponding decoder, transmitted by a carrier using an RF transmission medium and th12d output to the output pins after processing the data. Interface GPS with Arduino. To know how a 4-bit data can be encoded and then send to the input pin of this IC, we deccoder to understand the working of the HT12E Encoder IC which is given here.

HT12D is capable of decoding 12 bits, of which 8 are address bits and 4 are data bits. So out of the bits 8-bits will be used to set address and the remaining 4-bit will deecoder used eecoder transmit data. Customers who bought this product also purchased This pin will go high when a data is received.

The serial input data is compared with the local addresses three times continuously.
