Microcontroller › PIC › how to convert frm 2.5V to exact 5V?
hi guyz, any idea to vonvert 2.5V to exact 5V… the voltage frm output port is 2.5V someting which connected to RELAY.. but 5V is needed to activate that relay…
voltage is kind of energy, cannot be created nor destroyed. Thus, u need external source to power up.
