I connected the VMA05 on an Arduino Yun board, but the sample that is provided that should switch all relays does nothing.
No relays click and no LED’s on the board are turned ON.
I can send signals to PIN 13 on the Yun board and I see the small red led on the yun board being turned on, but nothing happens on the VMA05.
Any ideas what is wrong?
As opposed to the Uno for which the board is designed, the Yun does not supply power to the board.
You will have to supply 12VDC for the relays from an external source.
I allready connected a 12V power supply on the output side or do I need to connect them to something else?
Now it is: powersupply to ledstrip, ledstrip to Relay 6, Relay 6 to powersupply
I connected it to the relay with pin 1 and 3 and then the ledstrip is always on and I can’t turn them off.
If I connect it to pin “1 and 2” or “2 and 3”, they are off and I can’t turn them on.
Any suggestions?
By the way, I use these commands:
myArduinoYun.local/arduino/mode/13/output
myArduinoYun.local/arduino/digital/13/1 to turn relay on (I see status led on arduino turn on)
myArduinoYun.local/arduino/digital/13/0 to turn relay off (I see status led on arduino turn off)
The relay shields needs to be powered with 12V aswell.
And how do I power the shield?
Apply +12VDC to pin 1
Connect ground to pin 2
(see diagram in manual)
Make sure pin1 is disconnected from Yun.
OK, thanks, I will try it tomorrow.
Just to be sure, pin 2 already seems to be connected to the ground, so I can just leave it as it is, connected to the yun?
Yes, you can leave it connected.
