controlling a 5v relay throught usb port

[cpalka]

By the way

I think it will be start a new topic, but I would get some help to help me if it is possible build a temperature controller with:

- 1 usb to 232 profilic adapter (for reading DS18B20)

- 1 DS18B20 temperature sensor

- 2CH relay (for peltier element, cool and heat)

- 1 peltier element

My problem now is getting the the DS18B20 readings in labview. I could get it with 1Wire application.

Best regards

Hi !

I have a few 3 years old Relay boards which work fine with labiew.

Currently I bought similar relay (same microcontroller, CH340 driver), but provided commands doesn't work with LV.
