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.
