hello, i looked around the net the whole night for some info, but i haven't found anything, everything is out dated or doesn't fit my project.
basically i need to turn 3 of these relays on from a serial port
http://www.allelectronics.com/make-a-store/item/RLY-503/5VDC-4PDT-DIP-RELAY/1.html
i guess i can do a 4th relay that the serial port turns on and that 4th relay will turn the other 3 relays on, but im not sure what would be best, and exactly how to accomplish doing so, those relays are 5v, and the power supply im working with is 5v so that works out.
maybe i can modify this to work with my 5v?
