This project replaces the controller board in a Philips XXL Airfryer.
An airfryer contains the following elements:
- Temperature sensor
- Fan
- Heating element
- PSU
- Controller board (UI)
The first three components and the relays on the power supply (PSU) board were reused in this project. Keep in mind that the relays on the PSU needs 12V. Another option is to buy 5V relays.
Features:
- Persistent cookbook (using EEPROM memory)
- Multiple steps when cooking (different temperatures, timings).
- Delay cooking (act as a timer when temperature is zero)
- Preheat option.

Unfortunately the wokwi simulation can not simulate fast rotary rotations.
