I am interested in making a controller with a temp range of 100-1000 Degrees Fahrenheit. I currently use PID controllers for my projects but would like to have a little more versatility and would like to create a more simple user experience. I am using a 150 watt heater and k type thermocouple. I will use a SSR as the switch for the circuit. I need some advice/assistance with making a controller with a simple led display and and just an up(increase) and down(decrease) button. I do not have any experience with this so any advise would be appreciated. What components will I need. Which chip makes the most sense.
