Hi all,
New user here. I'm using Arduino Uno to control an 8-channel relay via the Serial Monitor. When I type in the number for any 1 of the 8 channels, the output on the corresponding pin is to be toggled.
I uploaded program using my laptop, and it seems to do what it's told. However, when I try to run it with my actual device connected to the relay (comprising a set of electrodes and a 50V ac signal to be switched by the relay), the Serial Monitor stops being responsive after a while (a minute of so). This seems to happen both on my laptop and desktop. When I check Serial Port, I find that the COM Port to which the Uno was originally connected has disappeared. In the case of my laptop, I can reconnect it by unplugging and plugging the USB cable, and then opening the Arduino software again; with the desktop, that does not seem to work.
Any idea as to what might be going on? I've attached my code.
Thanks a lot!!
