Step 1: What You Need?
Don't have components? Don't worry. Just click the component's name.Step 2: Build Your Circuit.
There is no circuit for this example, though your board must be connected to your computer via USB and the serial monitor window of the Arduino Software (IDE) should be open.
Step 3: Upload The Code.
1. Select the Arduino board type: Select Tools >> Board >> Select your correct Arduino board used.
2. Find the port number by accessing device manager on Windows. See the section Port (COM&LPT) and look for an open port named "Arduino Uno (COMxx)". If you are using a different board, you will find a name accordingly. What matters is the xx in COMxx part. In my case, it's COM3. So my port number is 3.
Select the right port: Tools >> Port >> Select the port number.
3. You can find this code in the example of Arduino IDE.
Select File >> Examples >> 08. Strings >> StringReplace
Click press the "upload" button (see the button with right arrow mark).
String stringOne = "<html><head><body>";
String stringTwo = stringOne.replace("<html><head></head><body></body></html>", "Blah");
In this case, the code will compile, but stringOne will remain unchanged, since the replacement substring is more than the String itself.Download:
