Hi All, Got an annoying problem with the usb connection to my laptop when I have a mains operated device connected to an output. The mains operated device does not work when the usb is connected.
Does anybody know why and more importantly how can I fix it? In just about any application using a computer you can look at your screen and see what is happening and even intervene as necessary. In a lot of industrial processes you have an operator sitting at a console seeing that the process is proceeding correctly.
I am using a nano board. It is not an arduino board but a clone from Jaycar.
Hoping somebody has a fix for this problem.
Show us a good schematic of your proposed circuit.
Show us a good image of your ‘actual’ wiring.
Give links to components.
It is not a proposed circuit Larry. It is a working circuit which I cannot see on my laptop as it is working unfortunately. Just need to know why.
What kind of device? I guess you did not design / build it yourself? Because if you did, you could provide the schematic. I suggest that you contact the supplier of the device.
Connected to what kind of output?
