“I am making an Arduino shield to interface with old Nokia phones. I’d like to keep the price around $20 for the shield, cables, and phone. If I can get some software help from the community, this will be great for interfacing projects with the internet.
For photos, code, and a detailed writeup please check out my post at http://paxinstruments.com/nokia-phone-arduino-shield/
- Should the shield be for a specific Arduino board or be configurable? The AltSoftwareSerial library uses specific pins for different Arduino boards.
- Is it fine to have the phone and serial-to-USB chip both connected to the Arduino RX/TX lines?
- Do we need the level shifters?
- Is there a better Nokia cable that also provides power?
- The Nokia 3100 needs a battery to run even with the power cable inserted. Is there a way around this?
- Is there a better target phone?
