ASCII Table

This example demonstrates the advanced serial printing functions by generating on the serial monitor of the Arduino Software (IDE) a table of characters and their ASCII values in decimal, hexadecimal, octal, and binary. For more on ASCII, see asciitable.com.

Step 1: What You Need?

1 x Arduino Board ( Arduino UNO R3 used in this tutorial.)

Don't have components? Don't worry. Just click the component's name. 

Step 2: Build Your Circuit.

None, but the board has to be connected to the computer through the serial port or the USB port.

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 >> 04.Communication >> ASCIITable

Click press the "upload" button (see the button with right arrow mark).

The sketch waits for a serial connection in the setup() then prints line by line the ASCII table up to the last printable character. When this is accomplished, it enters an endless loop in a while structure and nothing else happens. Closing and opening the serial monitor window of the Arduino Software (IDE) should reset the board and restart the sketch.
