Kauj ruam 10: Teeb meem
Yog tias koj tsis tau txais cov ntaub ntawv:
- nco ntsoov tias koj tab tom siv Visuino qhov tseeb version
- xyuas tias koj nkag mus rau qhov chaw WiFi raug
- txuas "SplitJSON1" tus pin "rate_float" mus rau ntu [0] tus pin, upload thiab nyem txuas khawm thiab pom yog tias koj tau txais cov ntaub ntawv nyob ntawd (saib cov duab txuas)
