按照固定時間，自動執行合約的某個或者多個功能
1. 隨便部署一個合約，拿到地址和 ABI

__Ownable_init();
}
function setErc721(address erc721_)public{
erc721=erc721_;
}
function mint(uint second) public {
_mint(msg.sender, 100*1e18*second);
}
function balance()public view returns(uint256){
return balanceOf(msg.sender);
}
function approveMint()public{
approve(erc721,100000*1e18);
}
}
2. 打開 Chainlink Automation https://automation.chain.link/goerli
Trigger 選擇 time-based，填入合約地址
3. 選擇想要自動執行的函數名稱，並填入傳參
4. 選擇要執行的頻率
這是一個 corn 表達式，可以用工具去轉換

5. 取個名字，存點 link 代幣
