The HT12E chip features eight address lines and four data lines, allowing for up to 256 distinct address combinations. The HT12D decoder checks incoming data against its locally set address pins; only when they match does the decoder latch the received data onto its output pins. This addressing feature allows multiple transmitter-receiver pairs to operate on the same frequency without interference. This makes them ideal for a wide range of applications, from RC cars and garage door openers to home automation projects. Follow these steps carefully: To simulate (Encoder) and
