Brewpi sainsmart 2 channel relay

I wired every thing up and I have checked it twice. The light turns on IN1 and IN2 when it should but bo click and no power to outlet. Maybe a bad relay or something else looking for some advice

 

Are you powering the relay module VCC with 5V?

Cheers!

 

Thank you that fixed it... Didnt notice unit you said something that it was in the 3.3V and not 5v

 

Nbd, that's a pretty common thing...

Cheers!

 

I have the new BrewPi Spark v2 Controller https://store.brewpi.com/featured/brewpi-spark-v2 and I am trying to get it to control the Sainsmart 2 channel relay. I notice that the digital output is only @4.8v not 5v ... could this cause the relay to not "click"?

On the 4 PIN [GND, IN1, IN2, VCC] I connected:
BrewPi Digital Out (set 0) + <----------> IN1
External Power 5V + <------------------> VCC
External Power - <------------------> GND

On the 3 PIN side of the realy [JD-VCC, VCC, GND]:
The jumper was on the JD-VCC & VCC
The GND was not connected to anything

I have verified that the relay does in fact work. I have verified the touch screen on the BrewPi does in fact turn on/off the digital outs (each one is pushing 4.8V).

I am a NOOB when it comes to the relays and the hardware portion of this project I must admit, the schematic found here: http://www.sainsmart.com/arduino-pro-mini.html did not help me.

 

4.8V should be enough to make them work.
