HT12D is capable of decoding 12 bits, of which 8 are address bits and 4 are data bits. It decodes the serial addresses and data received by, say, an RF receiver, into parallel data and sends them to output data pins. They are paired with 2 12 series of decoders for use in remote control system applications. It is very important that your Decoder should also have this same address for them to talk to each other.

For decoding a data the IC will requires an oscillator, luckily this IC has one in-built. Supply voltage; 5V 2. These pins are generally shorted by a resistor. The encoded bit can be obtained from the Dout pin pin SPI Module of Arduino. You can know to set up the HT12D after this from here.


Now first of all let me acquaint you about these two integrated circuits: HT12E IC has four bit parallel data inputwhich it then converts to serial data output. This high-density System-in-Package SiP integrates controller, power switches, and support components.

HT12D Decoder IC

This data should be sent to the HT12D for decoding, it can either be sent directly through a wire or by using a wireless medium like RF or IR. A valid transmission in indicated by a high signal at VT pin.

This oscillator can be used by connecting these two pins through a 1M Resistor. Datadheet you want security you can connect any of the 8 pins to 5V to make it high.

In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground.

It encodes the 12 bit parallel data into serial for transmission through an RF transmitter. HT12E begins a 4-word transmission cycle upon receipt of a transmission enable. These two ICs together form an Encoder and Datasheer pair. Choosing Battery for Robots.

Pull the Transmission Enable pin pin 14 to ground to activate transmission. This cycle is repeated as long as TE is kept low.


To find out more, including how to control cookies, see here: Arduino based GPS receiver. Used for interfacing RF circuits generally MegaHz.

The Encoded 12 bit output data can be obtained from this pin. Can range from 2. This IC has a total of 18 pinsnine on either sides: In additional to itit also has 8 address lines which can generally be grounded along with the pin number hr12d.

They can also be connected to switches to manually send and receive data. The data on 4 bit latch type output pins remain unchanged until new is received. Interface GPS with Arduino. These ht122e bits are divided into 8 address bits and 4 data bits.

HT12E Encoder IC

This pin has to be connected to Ground 0V to enable the Transmission. They are paired with 2 12 series of encoders. This is an CMOS logic integrated circuit encoder. The input data code is decoded when no error or unmatched codes are found.
