HT12E is an encoder IC for RF and IR modules mostly. It is a 12-bit decoder that uses 8-bits for address and 4 for data. RF and IR modules can interface with microcontrollers directly which …

Make a RF Transmitter and Receiver With HT12E & HT12D: Would you like to send wireless data? easily and with no microcontroller needed? Here we go, in this instructable i'll show you mi basic rf transmitter and receiver ready to be used!

In this instructable i'll show you how to make a RADIO remote control using 433mhz transmitter receiver module with HT12E encode & HT12D decoder IC. The RF transmitter with and a good antenna can send data up to 100m (outdoor and no osbtacles). Operation voltage of RF receiver is: (5v - 9v). 9. VSS connected to GND. 10-13.

The 212 series of encoders begin a 4-word transmission cycle upon receipt of a transmission enable (TE for the HT12E or D8~D11 for the HT12A, active low). This cycle will repeat itself as long as the transmission enable (TE or D8~D11) is held low.
