Simply put, HT12E converts the parallel inputs into serial output. Interface GPS with Arduino. At low signal data is transferred via antenna and received by Receiver IC which then decodes it to original parallel data. For decoding a data the IC will requires an oscillator, luckily this IC has one in-built. What is Web Browser. This is an CMOS logic integrated circuit encoder.

I am now going to tell you about to control a certain robot wirelessly rather than using wires. The Encoded 12 bit output data can be obtained datassheet this pin. These four pins are used to send data, the data encoded here will be decoded on Ht1e2 IC sharing the same address bits.

HT12E Encoder IC

After one complete cycle of data transfer the pin TE goes in high impedance state, thus indicating 1 cycle of data transfer. In additional datashset itit also has 8 address lines which can generally be grounded along with the pin number 9.

In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins hh12e ground. You can know to set up the HT12D after this from here.

Generally a resistor of value 51 KOhms can be used. This IC has a total of 18 pinsnine on either sides: So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. HT12E is an encoder integrated circuit of 2 12 series of encoders. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc.

Can range from 2. Supply voltage; 5V 2.

HT12E Datasheet

This pin has to be connected to Ground 0V to enable kf Transmission. Arduino based GPS receiver. If you want security you can connect any of the 8 pins to 5V to make it high. Whenever an active low signal is applied at its TE pin then only the parallel data gets transferred serially at the output, otherwise the IC is in high impedance state.

Choosing Motor For Robots. The IC has a built in oscillator. SPI Module of Arduino. It is mainly used in interfacing RF and infrared circuits. The encoded bit can be obtained from the Dout pin pin Choosing Battery for Robots.

An LED can also be connected across this terminal to indicate output. In this image I have made all four data bits as zero lowwhen this is decoded we will get the same kind of bits on the output side of HT12D, similarly we can make any changes on these 4-bits and they will be reflected on the output side of the HT12D decoder IC. This IC hasmany applications in short range remote controlling. Skip to main content. These two ICs together form an Encoder and Decoder pair. It encodes the 12 bit parallel data into serial for transmission through an RF transmitter.


This site uses cookies. These are the 8-bit address bits, which is used to protect your data. This pin outputs the parallel data serially. TL — Programmable Reference Voltage. 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.

Gone are the days when we used to use wires to connect two devices to establish a communication path. Basically found in applications of remote control systems. Pull dataeheet Transmission Enable pin pin 14 to ground to activate transmission. This cycle is repeated as long as TE is kept low. Virgin Galactic — Commercial Space Flight. The IC is has a wide range of operating voltage from ht12ee.

Transmission enable; active low. To find out more, including how to control cookies, see here: They can also be connected to switches to manually send and receive data. This high-density System-in-Package SiP integrates controller, power switches, and support components. Used for interfacing RF circuits generally MegaHz.

HT12E IC has four bit parallel data inputwhich it then converts to serial data output. They are paired with 2 12 series of decoders for use in remote control system applications. The 4-bit data that has to be sent has to be given to the pins AD0 to AD1 and an address of 8-bit satasheet to be set using the pins A0 to A7. Interface SD Card with Arduino.
