Title: Problem Activiating Relay
Post by: jsmoker on April 05, 2007, 09:20:20 AM

I bought a few relays for a project from sparkfun.  At the same time I placed an order for a few PCBs on which the relays were to be used, unfortunately, after I got the relays I found that they don't activate until like 5.1 volts, just barely higher than the 5V of the board.  Does anyone have any non-invasive ways to solve this problem, ie, like a one component...back of the PCB soldering solution?

Yeah, I'm trying the transistor now, still not quite working....(See my other post).
