To simplify Boolean functions (or switching functions), one might use the Karnaugh map method when there are not that many variables used. However, if a greater amount of variables are used or if several Boolean functions need simplification, using a computer is ideal. The Quine-McCluskey procedure presents a systematic approach that can easily be programmed into a computer for digital simplification.

In the last installment, we built the hardware to control an AC waveform with a TRIAC as the first step in a DIY solder reflow oven. This tutorial continues the project by showing you how to set up the low-level hardware to measure temperature, read the zero-cross detector, drive the TRIAC, and print to the serial terminal using a USART.
