• Microcontroller Brown-out detection
  Most of microcontrollers have On-chip Brown-out detection, which monitors supply voltage level while operating. Brown-out circuit is simply nothing more than comparator, which compares supply voltage to a fixed trigger level.
  Mostly all microcontrollers have built in Brown-out detection (BOD) circuit, which monitors supply voltage level during operation. BOD circuit is nothing more than comparator, which compares supply voltage to a fixed trigger level.If microcontroller doesn’t have On-Chip Brown-Out detector, then there can be external circuit used :The circuit above illustrates the brown out detect

• Power up your electronics using potato batteries
  Did you know that potatoes can generate electric power. Check this out.
  Thomas Pfeifer does something new and amazing every day. This time he demonstrates how simple digital clock or LED diode can be powered by using batteries made of few potatoes and two different types of metal (iron and coper). Demonstration shows that such battery made from single potato generates 0.848V voltage and is able to [...]
