I followed a simple tutorial on setting up an RGB LED. The LED uses pins 11, 12 and 13. Via the serial interface I can issue commands such as the following:
The letters activate the color, and the number immediately after the letter specifies the brightness of the color.
That worked just fine. I then decided to find a way of controling my RGB project from a web interface. To make the connection to the internet, I mounted my Ethernet shield on my Arduino Uno, included a MAC and server IP address etc.
In my setup function, when I call
ethernet.begin(), I get very strange combined effects.
- The red aspect of my LED is permanently on
- My sketch no longer responds to my input
Can anyone offer any ideas why a call to
ethernet.begin() would have such negative effects, please ?
