Hello sir, I am new to embedded field, doing a project on data transmission using RF. In this project HT encoder & ht decoder IC’s are used. Problem. ht – send data from atmel to HT – 8 Bit Decoder& Encoder for RF / Mhz Rx-Tx – Confused in in HT/HT – how to transmit. The encoder is used for encoding parallel data for transmission feed while reception is decoded by a decoder. HT12E-HT12D, HTHT, etc. are some .

HT is an encoder integrated circuit of 2 18 series of encoders. It is mainly used in interfacing RF and infrared circuits. The decoder then retrieves the original parallel format from the received serial data.

I don’t know where you can get them in the Phillipines as I live in another country. RF module, as the name suggests, uses radio frequency to send signals. A receiver can receive these signals only if it is configured for that frequency. This transmitter has range of meters, 10 Jumper selectable addressing provide security and allows creation of multiple transmitter and receiver.
About Me – Feed Back – Review. Since only serial data can be transmitted, you also need an encoder and decoder. Whatever you transmit, is seen at the receiver. Since only serial data can be transmitted, you also need an encoder and decoder. Similarly at reception i decdoer to connect with ht Decoder.
The input signals, at the transmitter side, are taken through eight switches while the outputs are monitored on a set of eight LEDs corresponding to each input switch. Next, RF transmission is more strong and reliable than IR transmission.
Similarly at reception i have to connect with HT Decder. The transmitted data is received by an RF receiver operating at the same frequency as that of the transmitter. SPI Module of Arduino. RF communication uses a specific frequency unlike IR signals which are affected by other IR emitting sources.
Interface GPS with Arduino. I like this project. Hi Check your mail box.

Interface SD Card with Arduino. This high-density System-in-Package SiP integrates controller, power switches, and support components. The encoder is used for encoding parallel data for transmission feed while reception is decoded by a decoder.
Linear output pin; not connected. Ideally Address pin has 3 states high, low and floating in this project we have use only two states low or floating so combination are possible. A valid transmission in indicated by a high signal at VT pin. Simply put, HT converts the parallel inputs into serial output.
Jumper setting can be done via J1 to J10 in transmitter and receiver. If I press that h6t48 all data will turn on or not??
If I press that switch all data will turn on or not?? An RF transmitter receives serial data and transmits it wirelessly through RF through its antenna connected at pin4. They are paired with 2 18 series of decoders for use in remote control system applications. This cycle is repeated as long as TE is kept high.
