Stan (and others), I apologize. My issue was the need to LOW trigger 2 relays with one Arduino output. I assumed that since the relays were optically coupled, no problem. But I couldn't get them to activate with the LOW from the Arduino. Finally used brain, put VOM in series with relay trigger pin & ground and measured 1.2mA. So, problem was not an Arduino sourcing limit. Turns out it was a bad breadboard (very typical of stuff I've gotten recently). And Stan, by the way, I modified one of your previous circuits (with a transistor driver before I discovered real problem) and it worked great, but it should not be required.
