Program Flow
1: Download the program to the Micro:bit.
2: Press A and KOI will say “Hello” in English.
3: Press B and KOI will say “Good Morning” and “I am happy” in English.
| The text to speech function only supports short phrases(2-3 words) and there must be no spaces between the words. |
4: Press A and B and KOI will say “123” in Putonghua.
| MakeCode does not support Chinese chracters but BaiduAI does, so BaiduAI will treat numbers as Chinese. |

FAQ
Q1: There is no reaction after pressing the buttons on the Micro:bit.
A1: 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.)
Q2: Does KOI work with 3V input?
A2: No, KOI only works with 5V.
