Versatile Voltage-to-Pulse Train Converter Supports Sensor
Versatile Voltage-to-Pulse Train Converter Supports Sensor Data I/O

When the need arises to convert voltage readings from an analog sensor into a pulse train, a low-end microcontroller offers a versatile solution. The design uses an 8-pin PIC12F683 to provide a pulse train that’s proportional to the sensed input voltage. This is useful, for example, when transforming a sensor signal into a format that’s compatible with a basic digital or GPIO input...
