On the 315Mhz 2 channel Relay board, can the relays be operated independently of each other using an external switch?
maybe I get your question wrong, but each relay is independent. 
If I close the switch both relays energize at the same time. I was wondering if it is possible to operate them one at a time.
Also, I cant seem to get the relays to work in FLIP-FLOP mode. The relays energize when I close the switch but once the switch is opened (momentary) the relays de-energize.
Any help would be greatly appreciated.
