# orsala_hack: reconstructing IKEA ORSALA lamp controls

> orsala_hack reconstructs the control behavior of the IKEA ORSALA lamp in replacement STM8 firmware. It documents the original rotary-encoder actions, MCU and LED-driver connections, and changes brightness, color-temperature and power controls while saving settings to EEPROM.
