Salutations Raspberry Pi Forum Browsers!
I am a senior undergraduate student in chemical engineering. For my senior design project, I have been tasked with building an automated temperature controller for a kamado-style smoker, like the Big Green Egg. After researching the subject extensively, most similar projects I have found online have been seemingly complicated from a hardware standpoint (at least for someone who has little background in electronics). For example, this project (https://github.com/CapnBry/HeaterMeter/wiki) includes tons of resistors, capacitors, etc. For the project, I would need ways of connecting type K thermocouples (at least 2) to a Raspberry Pi, and a way to connect a variable speed blower (controlled by pulse width modulation) to a Raspberry Pi. Is all of the complex circuitry in the project above necessary for this?
From my understanding, I should be able to execute the above functions with a thermocouple amplifier breakout board such as the MAX31855 and somehow modifying some of the GPIO pins for pulse width modulation to control a variable speed blower. Is this correct? Any pointers or explanations I can get would be helpful.
