I'd like to use a transistor PNP like a reverse switch, so when i cut the blue cable in the picture i want to turn on the current in pin 8 of Arduino... i think i made a wrong circuit in the picture... this is the datasheet of the transistor(mine is bc557).. can you show me the correct circuit? than…
