i bought one of those generic PCBs it looks just like a bread board but it just need soldering
i have some questions
first as the red arrow number 1 shows what is the point of those rails? the buzzer doesn't detect any current flow in it.
question 2 can i cut through the pcb through the blue line shown?
question 3 i've seen videos showing how to solder on pcb and usually they solder on the back of the pcb but when i tried i failed and only i succeeded in soldering on the shown upper face.
thanks
