Microcontrollers come in all sorts and sizes, and it’s very tempting to use them everywhere. If you are in a plan to build your own Vending Machine, probably you need a microcontroller-compatible Drop ...

This idea describes an MCU interface for a 1-Wire temperature sensor interface that offers high accuracy while using less board space. The circuit can be modified for use with any 1-Wire device. The ...

Finger sensor circuit diagram showing sensing traces (33), drive/shield electrodes (35) and switches (42, 43). When not being used for fingerprinting purposes, the drive/shield electrodes can also be ...
