# 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.
