As i try to connect my motor shield i put it in my arduino board. As soon as I plug my USB cable in it i get no respond from arduino board. But when i touch bottom of arduino board with my hand A and B lights up. I have no clue what is wrong with my arduino board. I connected it with my battery supply 6 V for AA- batteries nothing happends. I also plugged extra power supply into blocks next to A, B - motor input, no results.
I'm really desperated because it is my school's project !
there is no error message. I'm able to upload my code succesfully . I''m using arduino motor shield R3.
I meant that when I touch back of arduino board where you see pin's , motor shield starts to work and light called A and light called B on motor shield lights up and everything works fine. But when i take my hand away and lay it on table for example only green light and orange light works on arduino board, only thing that works on motor shield is reset button.
I could not able to understand this. What sort of thing ur trying.you have any electrical power???

It might some loose connection.From fig you meant to say . when you hold both board tightly A and B Arduino Motor Shield R3 Front
will blink , If you move your hand stop blinking.
... not shur if I understand your problem...
Could it be you have left open some pins on the shield (enable, powersave) without connecting them to ground or high.
This way they will swap (enable disable the motoroutput or what ever in a short time) - and maybe are set to ground/high when you lay your hands on the board...
