I’ve eight 12 volt dosing Pumps that I want to connect to ferduino controller
I’ve two Relays boards with eight 12 Volt channels
But when I connect correctly to arduino and only
Take some test code Relays Board flashes but in Relays nothing happens
I put Relays 8 to pwm8 port
Then +/- from Arduino Mega into Relays Board
Then I connect external 12 volt power adapter (+) to the pump (+)
And (-) to middle screw Relays 8
And the (-) from the pump to the connect screw on Relays 8
Start test upload but the pump do nothing
Whats wrong

Hi!
What's the reason to use a relay board for dosing pumps if an ULN2803 is more cheap and very small? Moreover the wiring is very simple.
Please show me the model of your relay board and pictures of your wiring.
Best regards.

I used this diagram and look for other
Settings but nothing happens
Relais don’t go to on and off
http://www.gunook.com/home-automatisier ... zu-arduino
Link plus from power 12 volt to com and plus from pump to NO on Relais and change settings
And now I have this Relais then I can use them.

Hi!
Don't connect JD-VCC to VIN because the diode in Arduino can work only with 1A.
Remove the jumper then connect external 12 V power supply to JD-VDD and GND on this header.
Then connect connect 5V from Arduino to VCC and GND to GND.
To test the circuit you can connect IN1 - IN8 to GND if this relay board is LOW trigger (active LOW) otherwise connect to 5V.
Best regards.
