I recently bought an Official Arduino Uno for me to do some prototyping projects.
So far I have done a lot of projects with my Arduino Uno and decided that it would be helpful if there are up close and personal photos of the Arduino Uno Revision 3 that is why I am creating this post.
Board Model: Uno R3 (Revision 3)
Open Source Eletronics Prototyping Platform
Made in Italy
The pins that you see with the tilde (~). It means that you can use it for PWM (analogWrite).
I hope this helps for you to get up close and personal with the Arduino Uno.
