Hi!
Great to see the India forum spawn!
I'm Avik, a big-time Arduino enthusiast. I mostly use Arduino to interface with modules. GSM, GPS, RFID, Biometrics, Bluetooth & Wi-Fi to name a few.
On a little more interesting part, I'm using a Cisco router as the Wi-Fi module. It runs a tiny distro of Linux and is connected to the Arduino over a serial connection. I am currently in Bangalore and am pretty well versed with SP Road!
