- create a blank file in the file explorer (by clicking the + icon) and give it a name.
- copy the code below.
- compile the code.
- click the Run & Deploy icon in the icon panel.
```
pragma solidity >=0.5.1 <0.6.0;
contract Donation {
address owner;
event fundMoved(address _to, uint _amount);
modifier onlyowner { if (msg.sender == owner) _; }
address[] _giver;
uint[] _values;
constructor() public {
owner = msg.sender;
}
function donate() payable public {
addGiver(msg.value);
}
function moveFund(address payable _to, uint _amount) onlyowner public {
uint balance = address(this).balance;
uint amount = _amount;
if (_amount <= balance) {
if (_to.send(balance)) {
emit fundMoved(_to, _amount);
} else {
revert();
}
} else {
revert();
}
}
function addGiver(uint _amount) internal {
_giver.push(msg.sender);
_values.push(_amount);
}
}
```
For the purpose of this tutorial, we will run the `JavaScript VM`.
This simulates a custom blockchain. You could do the same using a proper backend node.
Let's deploy the contract:
Click the `Deploy` button
You'll see the deployed instance (AKA the udapp).
Then open it up (by clicking the caret).
We are going to call the `Donate` function and will send it ether.
To do this: in the value input box put in **2** and select Ether as the unit (and not wei like I did in the image below - well you could - it won't really change anything).
Then click the `Donate` button.
This will send Ether to the this function.
Because we are using the `JavaScript VM`, everything happens almost instantly. (If we had been using Injected Web 3, then we would have to need to approve the transaction, pay for gas and wait for the transaction to get mined.)
Remix displays information related to each transaction result in the terminal.
Check in the **terminal** where the transaction you just made is logged.
