- An iButton's temperature data can be read by an Android smartphone via a USB On-The-Go electrical connection. Power supplies edit Apple MagSafe and MagSafe 2 connector-equipped power supplies, displays, and Mac laptops use the 1-Wire protocol to send and receive data to and from the connected Mac laptop, via the middle pin of the connector.
- I'm using the following code with a Basic Stamp 2p to write and read information to a DS1996L iButton. 'WriteRom: TA = $0000 tempVar1 = $55 tempVar2 = $66.

DS1971 256-Bit EEPROM iButton™
The DS1971 256-bit EEPROM iButton™ is a rugged read/write data carrier that identifies and stores relevant information about the product or person to which it is attached. This information can be accessed with minimal hardware: for example, a single port pin of a microcontroller. The DS1971 consists of a factory-lasered registration number that includes a unique 48-bit serial number, an 8-bit CRC, and an 8-bit Family Code (14H) plus 256 bits of EEPROM. The power to program and read the DS1971 is derived entirely from the 1-Wire™ communication line. Data is transferred serially via the 1-Wire™ protocol, which requires only a single data lead and a ground return. The 48-bit serial number that is factory-lasered into each DS1971 provides a guaranteed unique identity, which allows for absolute traceability. The durable MicroCan package is highly resistant to harsh environments such as dirt, moisture, and shock. Its compact button-shaped profile is self-aligning with cup-shaped receptacles, allowing the DS1971 to be used easily by human operators or automatic equipment.
According to the schematics, I took my Arduino, a breadboard, the iButton reader, a 2,2 kOhms resistor, three wires and a LED. Detailed map middle earth hobbit. I wired it a little bit different than the drawing. My iButton reader had only two wires. A wire from 5V on the Arduino to the + lane on the breadboard; the resistor from the + lane to the first lane on the breadboard.

RW1990 iButton for Write and Read with Green Key Fob. RW1990 is a rewritable iButton intended for copying the keys of the Dallas DS1990A-F5 family (TM1990A-F5). The most common blank for copying electronic keys (tablets) from door phones. It is an electronic rewritable medium of 64-bit identification code. IButton: An iButton is a microchip similar to those used in a smart card but housed in a round stainless steel button of 17.35mm x 3.1mm - 5.89mm in size (depending on the function). The iButton was invented and is still manufactured exclusively by Dallas Semiconductor mainly for applications in harsh and demanding environments.

About Readers & Probes
iButton readers & probes are used to read and input information from iButtons.
Some readers, such as the iButton Serial Typer, use simple writing software to obtain and write the unique iButton ID in seconds. Other readers, such as the LinkUSBi Touch and Hold can be used to 'mission' or configure iButtons.
