Hi, I'm trying to build the Wall-E robot using wifi. I am using the UART-Wifi suggested. Do I need an arduino to make this work with EZ-B? And I tried downloading the wifi software from elechouse but it gives me a .rar file which tries opening with iTunes. I can't find the .exe file? This project is due in a week as a CAPSTONE project for my school and I am pretty behind. If anyone can help I would appreciate it!
