hi there,i have a enquiry abt this encoder. This encoder has 8 address lines, what does the address line actually do? wat i think is its juz a form of identification for the decoder to noe. so does it mean tat,i can connect the address lines all to VCC and then connect the decoder address line also to VCC,so both will be '11111111'...or do i have to connect it to ports or juz vcc and gnd? i am really confused abt the connections of the address lines...
yes, the address lines give you a way to change the code, like the DIP switches on a garage door opener. The encoder and decoder have to be set to the same address in order for the signal to go through.
