 i have 5 servos which need 5v pin i have only one of it in my board now what help me.

Daisy chain the power lead

Daisy chain the power lead (from the board to the first one, from thre to the second, etc) but you may or may not have enough power on your board - what is the board?

connect a jumper from that

connect a jumper from that 5v pin on your board to the breadboard…

in this way u will get many 5v connections…

Hope it helps…

A recommendation

Find the regulator model number, then google it with the keyword “datasheet”.  Check the specs for the output current capability and make sure it can provide enough power for all your servos.

I also recommend distributing the 5V line using a “hub” instead of daisy chaining many servos.  Its not that daisy chaining won’t necessarily work, but it will help balance power to the loads.
