Step 1: The Schematic
Make this up on your breadboard!
Step 2: Now Upload the Code
Make sure to change the IP address so it works with your router then upload it to your Arduino.
Step 3: Connect Up:
You now need to connect up the Ethernet cable to your router and plug in your Arduino to start the program.
Step 4: The Challenge:
See if you can make it move when connected to other Wi-Fi networks other than your own. You will need to go into router settings to do this so make sure you know what you are doing because if you change the wrong setting(s) you might be locked out and unable to change it back.
