Hello all,
I am currently working on a project that uses relays, a little different than the one found in your article here.

http://waihung.net/bluetooth-controlled-relay/

I've attached a picture below of both the relay module and the bluetooth (JY-MCU HC 05). I am using the Arduino Uno as of now and the IN1 and IN2 from the relay module are in pins 6 and 7 respectfully. I modified the code that was provided in order to control 2 relays instead of one. I've attached the code also.

As of now, I can get the IN1 connected relay to turn on and off but not the 2nd relay, I am wondering what I am missing in my code that would make this work.

Additionally, I had to split the wires leading from both the relay module and the bluetooth module in order to connect both to the 5V pin on the Arduino. Is there a better way to do this? because both need a source of power.

Thanks!
