In simple terms, HT12D converts the serial input into parallel outputs.

Interface GPS with Arduino. Submitted by admin on 27 October 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 address data as 0b, by connecting all address pins to ground.

How IC HT12D works?

Choosing Battery for Robots. Arduino based GPS receiver. Supply voltage; 5V 2.

So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. SPI Module of Arduino. The IC has a built in oscillator. These are the 8-bit address bits, which is used to protect your data.

They can also be connected to LED to physically view the received data. The IC is should be powered by 5V pin 18 and the ground pin pin 9 is grounded.

Valid transmission; active high. What is Web Browser. 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.

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

HT12D RF Decoder IC Pinout, Details, Equivalent & Datasheet

HT12D is a decoder integrated circuit that belongs to 2 12 series of id. If you want security you can connect any of the 8 pins to 5V to make it high. If any valid data is received they can be obtained from these four pins.

This oscillator can be used by connecting these two pins through a 1M Resistor.

The Encoded 12 bit output data obtained from HT12E has to be given here. We should set the bits in same pattern on Encoder and Decoder IC to ht12c them.

HT12D Decoder IC

Skip to main content. 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. Interface SD Card with Arduino.

This series of decoders are mainly used for remote control system applications, like burglar alarm, car door controller, security system etc. To know how a 4-bit data can be encoded and then send to the input pin of this IC, we have to understand the working of the HT12E Encoder IC which is given here. This oscillator can be used by connecting these two pins through a 1M Resistor 17 Valid Transmission VT This pin will go high when a data is received.

Virgin Galactic — Commercial Space Flight. It is mainly provided to interface RF and infrared circuits. In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. It is very important that your Decoder should have the same address of that of the encoder.
