Hi
Just thinking at the moment. I would like to use a MS Excel spreadsheet (using vba macros) to turn on/off some relays and/or opto isolators. Without being too complicated. Excel coding ok, but I need some advice on type of to use. There are a lot of circuits using parallel ports but nothing for USB I can find. Also is it possible to use ethernet?
Say with USB would I use a USB/ttl converter?
Futurlec have a mini board for opto isolators that looks ok. https://www.futurlec.com/Mini_Opto_Isolator.shtml
Trying to keep the cost down and complexity.
Thanks
