please suggest me the components required.

[mridulstudent20]

So it means it will work....

[mridulstudent20]

Will this work with a 4*4 matrix keypad which produces same frequencies that mobile produces.

WHERE CAN I PURCHAS ALREADY MADE DTMF DECODER $ HOW MUCH

[sasi bindu]

which cell phone model i can use sir?.how to know a cell phone is working with DTMF or not?

[Avadhut.Deshmukh]

only nokia old !

samsung not working !

[Chebog]

Sir, Good day, I'm going to ask if where do i put the separate voltage for the MT8870 decoder IC? and can you please guide me in how to mount the earplug to the circuit?

[robot1398]

where did you get the atmega in india

[Avadhut.Deshmukh]

Atmega16 it is widely available everywhere ! http://robokits.co.in/

[robot1398]

and the programmer

[Avadhut.Deshmukh]

6v only without voltage regulator

[vaidya]

how to connect ear phone with it???which wire we should give to the input dtmf decoder ... and which should be grounded????

[Avadhut.Deshmukh]

tip=tone and ring=GND

tip to green wire from jack and black to GND from Jack to connect ear phone done :)

[ajinkyadixit]

can i use 80v51 RD2 OR 8051 MICROCONTROLLER ?????
withe same code???

[Avadhut.Deshmukh]

Same no !

[mudz_07]

sir how did u connect the mt8870 DTMF to not gate and to atmega 16?..

[kevinmaru28]

can u please tell me what would be total cost of project (cost of components) in rupees

[Avadhut.Deshmukh]

Rs.500-1000/- low price ! ! :)

[aliyevzaur1989]

Dude....cut or clean your nails.....so disgusting...

[Avadhut.Deshmukh]

ok i work PCB black

nail sorry !!

[varunkmanikandan]

how to burn the atmega 16

[Avadhut.Deshmukh]

AVR ISP programmer burn !!!! Yes !

[kpkpkalpesh]

really nice project dude................

[skumar mahalatkar]

how to identify Ring & Tip in Ear Phones???? and can v use any mobilephone @ robot end!!!

[fmazi]

interesting stuff

[pkumar10]

did you use ceramic capacitor of "0.47micro farate" ??. I have used electrolytic but circuit is not working.
plz rply soon..............
