MySQL Connector/Arduino Example : connect
|
|
|
|
This example demonstrates how to connect to a MySQL server from an
|
|
Arduino using an Arduino-compatible Ethernet shield. Note that "compatible"
|
|
means it must conform to the Ethernet class library or be a derivative
|
|
with the same classes and methods.
|
|
|
|
For more information and documentation, visit the wiki:
|
|
https://github.com/ChuckBell/MySQL_Connector_Arduino/wiki.
|
|
|
|
INSTRUCTIONS FOR USE
|
|
|
|
1) Change the address of the server to the IP address of the MySQL server
|
|
2) Change the user and password to a valid MySQL user and password
|
|
3) Connect a USB cable to your Arduino
|
|
4) Select the correct board and port
|
|
5) Compile and upload the sketch to your Arduino
|
|
6) Once uploaded, open Serial Monitor (use 115200 speed) and observe
|
|
|
|
If you do not see messages indicating you have a connection, refer to the
|
|
manual for troubleshooting tips. The most common issues are the server is
|
|
not accessible from the network or the user name and password is incorrect.
|
|
|
|
Note: The MAC address can be anything so long as it is unique on your network.
