Here we designed a simple non contact tachometer using microcontroller which can measure speed with an accuracy of 1 rev/sec. Here we design a simple non-contact tachometer using microcontroller, ...

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 ...

This design implements a charger for a lead-acid battery as a subfunction in a microcontroller whose main function can be any more complex task. Furthermore, the MCU gets its power from the same ...

Using a MOSFET as a switch is generally pretty simple. Make the gate voltage sufficient with respect to the source and current flows through the channel. However, if you are switching higher voltages, ...
