| Console Pixel | |
| An example of using YunShield/Yún board to receive data from the | |
| Console on the Yún. In this case, the board turns on an LED when | |
| it receives the character 'H', and turns off the LED when it | |
| receives the character 'L'. | |
| To see the Console, pick your Yún's name and IP address in the Port menu | |
| then open the Port Monitor. You can also see it by opening a terminal window | |
| and typing | |
| ssh root@ yourYunsName.local 'telnet localhost 6571' | |
| then pressing enter. When prompted for the password, enter it. | |
