I'm a third year engg. student from Pune.....I'm doing a project about 'Retina Controlled Bot'.....I've used HT12E as encoder IC and HT12D as decoder IC.....I've built my own circuits of transmitter module and receiver module with encoder and decoder in them respectively,which are working properly....Now,only problem is that the circuit which I built is a bit difficult to explain....So can anyone please come to the rescue there?....I'm in deadly need...the project is supposed to be submitted before April's first week.....I'll accept a Ppt. presentation gladly,if anyone's providing that too.....
