This is just a basic prototype shield where you can experiment with your arduino projects.
There is a power LED which just comes on when there is power to the prototype shield.
Another feature is the LED which has a pad which you can connect to any arduino PIN and switch it on and off.
There is a reset switch which is connected to the arduino reset. In addition there is a button which like the LED can be connected to any arduino pin.
The LED’s and resistors are SMD versions so that the area for prototyping is maximized.
