"Professor Rao said all the parts were in the standard library," she muttered, her third coffee growing cold. "He lied."
She checked the spelling. HT12E. Correct. She checked the library. Nothing. Only generic 555 timers and 741 op-amps. ht12e and ht12d library for proteus download
Her heart sank. But wait—she forgot the virtual oscilloscope. She connected a probe to the DATA OUT of the HT12E. A beautiful, clean 3kHz pulse train appeared. "Professor Rao said all the parts were in
On the receiver side, she connected the DATA IN of the HT12D to a virtual terminal. Then she pressed the button again. Correct
But instead of the beautiful green "SIMULATION SUCCESSFUL" message, a red box screamed:

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.
