Pneumatic System not working

Hi, I am doing a final year project on a rehabilitation glove. I have 5 soft actuators I want to inflate and deflate using the control system shown in the picture. When I run the code shown, one air pump motor makes some noise but there is no air being produced. I have copied the layout of the schematic and I am not sure where I am going wrong. I am new to arduino and this would be one of my first times using the software. Could it be that my air pump motors are faulty ? [image] [image]
