I still cant understand about Vin. Please Explain Is that having any specific value?
Is Vin an input to 'Power'? What should i do with Vin?
Are Vin & Vcc 2 separate power sources?What's r2 100_NM & r3 100_NM? Are they capacitors? What are its values?
What is difference between Vin,Vcc, Power connector?
That's the external power connector. A 7-12vdc wall wart power module or a battery can plug into that connector if you are going to use external power for the board.
I connect a 9V battery instead of wall wart module to supply power for it. If I do so should I connect another power source for Vcc?
What is value of Vcc?Vin is the external voltage (7-12vdc), it wires to two places the input of the voltage regulator (IC2) and pin 1 of the shield power connector. There is no connection directly to the atmega chip as anything over +5vdc would destroy the chip.
Also where is that "shield power connector"?
