DS1307 RTC Emulator – The Arduino library

Things must come to an end. I decided to make a new library experiment, putting an ending mark to the DS1307 Real Time Clock hacking project, because the project was born as an encapsulation of a real RTC in a PIC microcontroller, wrapping an RTC hardware engine to emulate the DS1307; then a subsequent development on … Leggi tutto DS1307 RTC Emulator – The Arduino library

Tiny, robust, low cost, fail-safe LED driver: the Glighter-S project

It has been a while since the last LED related article. Was experimented the linear current source, its pros and cons and the field of application. Now arises the need of a small version, handling the same high power, things that are contrapposed in the linear regulator. I need something that I can bring with … Leggi tutto Tiny, robust, low cost, fail-safe LED driver: the Glighter-S project
