Many small microcontrollers require so little power that often they can draw what they need through their loads. This can simplify a system, reduce its cost, increase its reliability, and provide ...

The MCP120 is a microcontroller voltage supervisory circuit with open drain output. This voltage supervisory device is designed to hold a microcontroller in reset until the supply voltage has reached ...

This 8051 microcontroller-based control circuit adjusts the speed of a small permanent-magnet dc motor via photosensors (see the figure). The circuit can find applications in light-tracking systems ...

Slimmed-down version of Python, rebuilt from the ground up, is designed to run fast and lean on microcontroller hardware The Python programming language’s flexibility and ease-of-use have made it ...

This simple 4093-based audio peak detector from December 2004 monitors music and turns on a small light when the sound gets ...

It’s generally pretty easy to spot a microcontroller on a PCB. There are clues aplenty: the more-or-less central location, the nearby crystal oscillator, the maze of supporting passives, and perhaps ...
