I am new to the world of Arduino and have never used one nor programmed one. I am interested in creating a controller based on an Arduino to control a 5500 watt heater element in my beer brewing boil kettle. I do not need full PID control. What I envision is a controller that uses a rotary encoder to tell the Arduino a value between 0 and 100 that would correspond to duty cycle for the heater element. The Arduino would control an SSR with an overall cycle time of 10 seconds. So 100% would be 10 seconds on and 0 off. 77% would be 7.7 seconds on and 2.3 seconds off. I would also like to include a digital dispaly that would show the duty cycle selected by the rotary encoder. Any help would be appreciated. I am comfortable working with hardware, soldering, and mains power but have zero programming experience.
