Mar 11, 2009 Maxim's iButton® products are designed so that a personal computer (PC) can easily read from or write to an iButton device. The OneWireViewer is a convenient demonstration software program that allows users to easily read from and write to iButtons with a Windows-based PC that has a USB port. According to the schematics, I took my Arduino, a breadboard, the iButton reader, a 2,2 kOhms resistor, three wires and a LED. 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.
About Readers & Probes
iButton readers & probes are used to read and input information from iButtons. Sap sapcar exel.
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.
