I need help connecting landline phone to arduino. The phone needs to be unmodified and work as it did when wooked to the phone company. The arduino code that you all give me needs everything labeled for a dummy (myself). The phone is an analog and need landline for the power sorce.
Which Arduino, and what is the Arduino supposed to do?
The arduino code that you all give me
Consider asking the moderator to move this thread to the "Jobs and Paid Collaborations" forum section.
The board is an arduino uno. The phone need to work like it once did when hook to the landline. I only want the basic for all phone functions. Everything beyond the basics i can do once the phone operates as a landline phone.
The landline phone needs to be an interface for the arduino uno. The phone has a keypad buttons (3 x 4). I want the phone more like an add on to the arduino uno.
For the phone to function as a landline phone, the wires to the phone must come from a circuit imitating the telephone landline circuit. From there, another circuit will be required to translate the landline signals into Arduino compatible analog signals. The Arduino Uno analog output (PWM) may require some additional circuitry for generating the audio; if this is not good enough, a separate DAC will be required.
The quicker you provide information on this project, the faster the helpers here can start giving support instead of just asking questions.
As for someone creating the entire Arduino sketch, this type of request violates the intent of this support forum. The usual interaction here requires the requestor to make an attempt at the project and then clearly ask for help with a specific, clearly defined problem.
There is a section of this forum where people can find someone else to complete their project for them: the “jobs and paid collaborations”.
Good luck with your project.
I moved your topic to an appropriate forum category @scinceman.
In the future, please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.
This is an important part of responsible forum usage, as explained in the "How to get the best out of this forum" guide. The guide contains a lot of other useful information. Please read it.
Thanks in advance for your cooperation.
Define the basics, the Old Landline is known as POTS (Plain Old Telephone System). If you connect the two phones together and place a 3V battery in series with the connections you can talk. Love those old carbon microphones. To my knowledge the Arduino cannot do the voice to digital translation and everything else, you should use a CODAC (audio enCOder/DECoder) for the audio portion. The ring is about a 90V 20hZ signal at if I remember 600 Ohms. This allowed the phone when taken off hook short it out and stop the ringing. The CO (Central Office) would detect this and turn the ringer circuit off. That is just a small part, you want a lot please define what you want and how you expect it to work. You have a phone on one end and an Arduino on the other, how is it going to connect to the phone network. If you simply connect the phone it will probably work.

Your very BIG problem is a telephone is a CURRENT operating device while the Arduino signals are ALL voltage related signals. Some major engineering will have to go between the two devices.
No need for an Arduino, then.

You've got hold of an old rotary dial or otherwise an old telephone and you have also got an Arduino. You are looking for project ideas involving these two main components. If that is correct then you can search this site for actual projects. You'll find circuits to ring the bell, play music when you lift the hand set off the cradle, connect two phones together to make an intercom etc. etc. There are of course limits to the functionality that you can demonstrate on an old telephone which is not connected to the telephone network. You can't for instance dial your cell phone number from it and expect to get a response.
Old landline phone with push button keypad. 3x4 keypad
All I want is the ringer and keypad (3x4 push buttons)
With the phone functions unless you think its better to get bluetooth and build app for my smartphone.
@scinceman
You need to start over and explain exactly what you want to do.
What do yo expect the phone to do when it is connected to the Arduino? What do you want the Arduino to do when the phone is attached to it?
Do you expect to be able to make phone calls with this arrangement? Do you expect people to be able to call you?
There is a device called Magic Jack, It will interface your phone to the internet. Your cell phone can then call it. When you purchase it you even get your own phone number with a chance to chose what you want. To make it even closer to the old system it comes with voice mail and international calling (extra)
