I need 2 vcc pins on the arduino


I need to connect the vcc pin to a bluetooth module but then I need to sue it again for a relay module what do I do?

You just use the same pin twice. You can connect as many items to the 5V pin as you like as long as you don't draw more than around 750mA absolute max (the regulator is rated at 800mA, and the Arduino itself takes about 50mA or so of that).

Note that as you increase the current draw the regulator will get hotter, so if you want to use higher currents it would be worth investigating using an external 5V power source.
