HT12E is an encoder integrated circuit of 2 12 series of encoders. Choosing Motor For Robots. A basic datassheet diagram for the HT12E 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.
SPI Module of Arduino. So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. Pull the Transmission Enable pin pin 14 to ground to activate transmission.
HT12E Encoder 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.
Submitted by admin on 30 October Choosing Battery for Robots. These 12 bits are divided into 8 address bits and 4 data bits. HT12E has a transmission enable pin which is active low.
The Encoded 12 bit output data can be obtained from this pin. Skip to main content. In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. This pin has to be connected to Ground 0V to enable the Transmission.
We should set the bits in same pattern on Encoder and Decoder IC to pair them. Interface GPS with Arduino. As soon as TE returns to high, the encoder output completes its final cycle and then stops. Virgin Galactic — Commercial Space Flight. They are paired with 2 12 series of decoders for use in remote control system applications. Arduino based GPS receiver. For decoding a data the IC will requires an oscillator, luckily this IC has one in-built.
Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. The IC has a built in oscillator. The encoded bit can be obtained from the Dout pin pin TL — Programmable Reference Voltage. HT12E begins a 4-word transmission cycle upon receipt of a transmission enable.
Connected to the Ground of circuit. If you want security you can connect any of the 8 pins to 5V to make it high. Can range from 2. These are the 8-bit address bits, which is used to protect your data.
HT12E Encoder IC | HT12E Datasheet | Pin Diagram & Description
It encodes the 12 bit parallel data into serial for transmission through an RF transmitter. This oscillator can be used by connecting these two pins through a 1M Resistor. The primary function of HT12E is to encode a bit and send it out through the output pin.
The IC is has a wide range of operating voltage from 2. What is Web Browser. In this image I have made all encodre 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.
Transmission enable; active low. They can also be connected to switches to manually send and receive data. The 4-bit data that has to be sent has to ht12 given to the pins AD0 to AD1 and an address of 8-bit has to be dataseet using the pins A0 to A7.
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.
These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits. These two ICs together form an Encoder and Decoder pair. This high-density System-in-Package SiP datashret controller, power switches, and support components. Supply voltage; 5V 2.
You can know to set up the HT12D after this from here.
Simply put, HT12E converts the parallel inputs into serial output. It is mainly used in interfacing RF and infrared circuits.
This cycle is repeated as long as TE is kept low. It is very important that your Decoder should also have this same address for them to talk to encoser other. Interface SD Card with Arduino.
