Connect pins 10, 11, 12, and 13 (AD8–AD11) to SPST logic toggles or switches to simulate data input.
It was beautiful. It was the digital symphony he had been chasing all night.

To ensure your newly downloaded library functions perfectly, build this quick validation circuit:
: Connect pins A0 through A7 directly to ground ( GND ) to set a default address of 00000000 . Connect pins 10, 11, 12, and 13 (AD8–AD11)
Pull the Transmission Enable ( TE ) pin on the HT12E to ground. Run the simulation. Flipping the logic inputs should instantly update the state of the corresponding LEDs on the decoder side.
By utilizing high-quality library files, your Proteus simulations will be accurate, saving you time during physical prototyping. Default path (v8
