I believe that zombies are vulnerable to blunt impact trauma, provided it is directed at the cranium, and delivered with sufficient force.
The information backed by Day of the Dead ,Dawn of the Dead, Land of the Dead, Night of the Dead......Endless other classis American Zombie movies i have watched.
Good idea NI$HANT, the more specific hardware will depend on local suppliers too so I wish there were lists for parts suggestions say USA/UK/Australia/India/... where lots are playing with Arduino.
In places like India the main big distributors are not only distributing Arduino but also distributing stuff after importing from SparkFun so in nutshell everything is in reality American ,USA made or made on the same platform of the US developers, Hardly things are unique.
