About Heating Element
Heating Element usually has two pins:
- Positive (+) pin (red) needs to be connected to 12V of DC power supply
- Negative (-) pin (black) needs to be connected to GND of DC power supply
How to Control Heating Element
If 12V Heating Element is powered by 12V power supply, it emits heat. To control a Heating Element, we need to use a relay in between Arduino and Heating Element. Arduino can control the Heating Element via the relay. If you do not know about relay (pinout, how it works, how to program ...), learn about relay in the Arduino - Relay tutorial

The below code repeatedly turns the Heating Element ON in five seconds and OFF in five seconds,
- Connect Arduino to PC via USB cable
- Open Arduino IDE, select the right board and port
- Copy the above code and open with Arduino IDE
- Click Upload button on Arduino IDE to upload code to Arduino
- Check the Heating Element's temperature
Please be careful. It can burn you and your house. This is a serious topic, and we want you to be safe. If you’re NOT 100% sure what you are doing, do yourself a favor and don’t touch anything. Ask someone who knows! We do NOT take any responsibility for your safety.
