This Design Idea employs the Microchip PIC10F222 single-chip microcontroller. You program this microcontroller’s internal memory using the MCLR pin. As the title, “Use the MCLR pin as an output with ...

There have been many different ideas presented for increasing the acoustic output of a piezo buzzer or ultrasonic transducer. Most of them involve rather complicated circuitry that drives up the total ...

Temperature-indicator and temperature-based products have generated wide interest. There are numerous applications for such devices with many possible solutions, each with its own advantages and ...

The accompanying circuit maintains power to the load regardless of momentary shorts or opens in the supply voltage. The low-current overvoltage-protection IC (MAX6495) also protects the load against ...
