My audio jack does not connect to the mobile...i have used that audio jack previously for other projects...can you help please
Use another audio jack, 3.5 mm stereo male jack, left or right signal
@@SDevElectronics i ran out of time and had to change my project topic...but i will give it a try in the next semester ...thank you🤗
works rightly with cm8870pi?
Can i use MT8870 instead of CM8870.in some videos i have seen two 22pf capacitors near the crystal. Is it necessary?
Yes you can use it.Not necessary, if not working use it..It depends upon IC manufacturer
Please do you need to do programming?
No it's not programmed,buy and use
Can i use a 3.992mhz crystal??
Not sure, may not work
I want to buy blue mat.from where you buy
Background Green Mat:amzn.to/39ImLkA
How to convert the audio jack to the mobile connector. I know that the one pin is ground. What about the left and right audio pins.
Search in Google "3.5mm Headset jack pinouts"...
Can i use 9 volt EW CELL inspite of 5 volt??
No ...4.5V to 5.5V
Can this be used on landlines?
Sorry, I'm not tried yet...If you found 3.5mm female Jack on landlines, try it, reply me if it is working...
I know the "ring" voltage is much higher than the maximum supply voltage, so you may need something to prevent the initial voltage spike.
Hi bro I want the circuit diagram and how to connect breadboard connection place send bro
Circuit diagram inside this video..
What is the wattage of resistors
1/4 Watt
it doesn't work with smartphonesit only works when connected to basic mobile sets
May be
Diagram show
Inside this video, may be @ 3/4 of video
