I assumed thats what its designed to be. See the datasheet on usage.
hexadecimal decoder
AT89S52 is a microcontroller based on the Intel 8051 architecture and features. Concerning your question, AT89S52 is the heart of most project involving Dual Tone Multi Frequency (DTMF), that is to say it is the controller IC used in such project.
can i use ic 7476 as time delay
just conect gnd to the vcc
The 74138 is a 3 to 8 decoder. When enabled, one of the 8 outputs is low, based on the binary value of the 3 inputs.
basic operation of mobile controlled lies with the functioning of DTMF and L293D driver ic. one mobile phone is used to send DTMF tones to Rx mobile phone and DTMF decoder ic is used to decode the dtmf tones and it sends information to to micro controller which produces response according to program and gives control to l293d driver ic.
