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 ...

Although this circuit connects the DS18S20 1-Wire temperature sensor to a Cypress CY8C26443 PSoC microcontroller, designers can easily adapt it to connect other 1-Wire devices to any microprocessor.

This guy had the idea to make a high-speed photography setup using one, instead of the more direct circuits usually involved.
