SPI Module of Arduino. In simple terms, HT12D converts the serial input into parallel outputs.

What is Web Browser. For decoding a data the IC will requires an oscillatorluckily this IC has one in-built. The serial input data is compared with the local addresses three times continuously. Interface SD Card with Arduino. This oscillator can be used by connecting these two pins through a 1M Ht2d 17 Valid Transmission VT This pin will go high when a data is received. The Hg12d is should be powered by 5V pin 18 and the ground pin pin 9 is grounded.

The Encoded 12 bit output data obtained from HT12E has to be given here. Arduino based GPS receiver.


HT12D/HT12F – Product Details – Holtek

The input data code is decoded when no error or unmatched codes are found. It is not mandatory to use it. These two ICs together form an Encoder and Decoder pair. This oscillator can be used by connecting these two pins through a 1M Resistor.

HT12D Decoder IC

This high-density System-in-Package SiP integrates controller, power switches, and support components. A basic circuit diagram for the HT12D IC is shown below In the above circuit I have set the 8-bit datasheeet data as 0b, by connecting all address pins to ground. Supply voltage; 5V 2. HT12D is capable of decoding 12 bits, of which 8 are address bits and 4 are data bits.

It is mainly provided to interface RF and infrared circuits.

Choosing Motor For Robots. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. They are paired with 2 12 series of encoders. The data on 4 bit latch type datwsheet pins remain unchanged until new is received.

Submitted by admin on 27 October If any valid data is received they can be obtained from these four pins. The IC has a built in oscillator. We should set the bits in same pattern on Encoder and Decoder IC to pair them.


These are the 8-bit address bits, which is used to protect your data. TL — Programmable Reference Voltage.

Valid transmission; active high. A valid transmission in indicated by a high signal at VT pin. 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. It decodes the serial addresses and data received by, say, an RF receiver, into parallel data and sends them to output data pins.

Virgin Galactic — Commercial Space Flight. So if you are working on a project which has to transmit a 4-bit data from one end to other either by wire or wireless then this IC pair will be best suited for you.

It is very important that your Decoder should have the same address of that of the encoder.
