# **LCD Orientation**

One advantage of the KOI is that camera is able to rotate from 0°~180°, however the image may be reversed on the LCD when the camera is rotated, thus we may need to change the LED orientation based on our use case.

## FAQ

### 1: There is no reaction after pressing the buttons on the Micro:bit.

·    A: This is because KOI has a longer boot time than Micro:bit. When the power is turned on, Micro:bit has already ran the code for KOI initialization before KOI is ready.

·    Solution: Reset your Micro:bit after KOI has been turned on. (The trick is to let KOI power on completely before initialization.)

### 2: Does KOI work with 3V input?

·    A: No, KOI only works with 5V.
