Arduino Uno temperature controller

This is the code for my school project. It is a temperature controller for a Industrial heating rod embedded into a Aluminum mold (CNC).

Hardware

• Arduino Uno
• Aluminum mold (STL file included)
• Heating rod - Taken from a old soldering iron (Φ8mm)
• K Thermocouple with converter MAX6675
• Relay

Usage

• Connect the thermocouple to the MAX6675
• Connect the MAX6675 to the Arduino Uno
• Connect the relay to the Arduino Uno
• Connect the heating rod to the relay
• Open Serial Monitor to see the temperature and the relay state

#The code is based on the example code from the MAX6675 library

Planned features

• PID controller
• LCD display
• More heat-profiles
  • Ramp up
  • Ramp down
  • Hold Melting point
  • Heat-bed temperature
• Button for control
