µ[micro]electronics info

A weblog focused on interesting circuits, ideas, schematics and other information about microelectronics and microcontrollers.




Because I have not tested all electronic circuits mentioned on this pages, I cannot attest to their accuracy; therefore, I do not provide a warranty of any kind and cannot be held responsible in any manner.

OWFS - One-wire File System

OWFS is an easy way to use the powerful 1-wire system of Dallas/Maxim under Linux.

I2C example with the DS1307 RTC

An example of connecting I2C device to AVR - how to connect DS1307 RTC module with an Arduino?

AVR and 1-Wire interface

Dallas Semiconductor (Maxim) produces a family of devices that are controlled through a proprietary 1-wire interface. On a 1-wire network, a single "master" device communicates with one or more 1-wire "slave" devices over a single data line, which can also be used to provide power to the slave devices. How to connect such devices to Arduino?

PIC-based real-time clock with DS1307

This PIC project uses an I2C Real Time Clock IC (DS1307) and a four digit seven segment display to create a standard desk clock.

Electronic lock with iButton

Today I've found this interesting circuit, which In use Dallas/Maxim's iButton as a key to an electronic lock.
