Hi, I am totally new in Arduino, so far makes two projects to learn - blinking led and infrared control. On IR-control I am able to turn external LED on and off. Then I add 2-way wireless relay expansion board - just to have relay output. As per relay manual, relays connected to Arduino by pins 9 and 10. I did make my LED output on pin 9, but relay does not work. There is demo sketch for relay output, but if I will upload it, my IR will not work. Could some one help me, please. Thank you a lot.
Please post your code.
Also post links to your relay module
