Wireless RF Module Using PIC Controller !
Decoders compare the serial input data three times continuously with their local addresses. Capacitor (0.01uF) is used between Vcc and GND for noise filtering. Pin 17 (VT) is enabled whenever the receiver receives any data. HT12D is arranged to provide 8 address bits and 4 data bits. Address pins (A0-A7, pin 18) are grounded. Go Wireless !
