Know How... 300

Screens and buttons are nice, but it's time to add network capabilities to our Arduino projects. We're going to use an Ethernet shield with an Arduino UNO to build a few basic network-enabled gadgets.

 

Parts        
        
Geek credit UNO R3 ATmega 328P Dev Board    ~$4   
        
Geek credit Ethernet Shield Module W5100 MicroSD    ~$6    
        
- or -         
        
W5100 Ethernet Shield R3 (PoE)    ~$10    
        
        
Basics        
* There are examples of Ethernet projects build into the Sketch IDE        
        
Ethernet Server with Analog Input        

Code Example: _01_WebServer        
* Code for this example is under "File - > Examples -> Ethernet -> WebServer"        
        
* We need to change the following in the code:        
  -- Set the IPAddress to "192.168.0.229"        
  -- Change the "for" loop so there are only 2 Analog reads        
        
* We need to wire the following:        
  -- Power to the outer POT pins        
  -- Center pins to A0 and A1        
        
** Play with the "Refresh" setting to show a quicker refresh
