How I ran this project?

I started a live server from VS code of index.html
I have installed a Wallet called Metamask and loaded some Testnets
Then I typed my desired mood into the input box and clicked set mood
Metamask extension redirected me to the Payment page using Testnets I approved the transaction.
To check my transaction, I copied the transaction id and pasted on Etherscan
When it shows success, click Get mood
If it shows the mood you set, I'm done.
