I’m quite new to the world of Arduino, trying to learn the code to create my RF project.
Right now I have a basic script, that I’m trying to integrate with the Expander I/O shield module: http://learn.linksprite.com/arduino/shields/io-expander-shield-for-arduino/
The thing is, I don’t understand what is happening in the above installation.
This is the code I have so far, but i’m not sure if it all works. I’m just struggling to convert my current connections from the Arduino, to the I2C connection of the expander. The code isn’t great right now, but I cannot test and fix it without understanding the expander… online links don’t seem to help.
How can I use the pins in the example of my lcd declaration, led, buzzer etc?
