She placed the HT12E on the transmitter sheet, the HT12D on the receiver. She wired the address pins to ground (0x00). She connected a 1MΩ resistor between OSC1 and OSC2 on both ICs. She tied the TE pin of the HT12E to ground, enabling transmission. Then she pressed the first button.
Nothing.
But instead of the beautiful green "SIMULATION SUCCESSFUL" message, a red box screamed: ht12e and ht12d library for proteus download
On her laptop screen, Proteus 8 Professional glowed blue. She had drawn the transmitter section perfectly: a 4-bit DIP switch connected to pin 10, an oscillator resistor at pin 15, and the DATA OUT pin ready to feed a 433MHz RF module. On the receiver side, the HT12D was supposed to sit majestically, decoding the signal to light up an LED. She placed the HT12E on the transmitter sheet,
The Encoder, The Decoder, and The Missing Link She tied the TE pin of the HT12E
Maya opened her browser, fingers trembling. She typed: "ht12e and ht12d library for proteus download."
