Membuat project di arduino iot cloud dengan esp32

 1. pilih IoT Cloud

2. Create Thing

3. ketik nama project "kontrol lampu", kemudian klik add variable

4. isi  seperti bawah ini dan klik add variable

5. klik selec device

6. Set up new device

7. set up 3rd party device

8. pilih esp32 - dev module

9. ketik nama device "SIMOR"

10. catat secret key dan centang lalu  klik continue

11. done

12. set wifi, klik configure dibawah network

13. ketik nama wifi, password, dan secret key yangdi dapatkan tadi, klik done

14.  pilih dashboard dan build 

15. ketik nama dashboard kemudian klik add

16. pilih switch

17.  ketik nama widget dan link kan ke variable lampu

18. pilih thing - variable lalu klik link variable

19.  pilih thing kemudian sketch

20. full sketch

5.   The following variables are automatically generated and updated when changes are made to the Thing
6.   bool lampu;
7.   Variables which are marked as READ/WRITE in the Cloud Thing will also have functions
8.   which are called when their values are changed from the Dashboard.
9.   These functions are generated with the Thing and added at the end of this sketch.
