It was the arduino drivers incorrectly installed. Now it shows the MEGA on COM port 4 and the connection is stable (no more disconnects.) thanks. However, I am still unable to control the LED or getting a reading from the 1 wire even with the resistor I added. I've tried rebooting the arduino...

I'll be sure to add one. As for the serial disconnects and being unable to control the onboard LED, here is my communications log. Edit: I did change the firmware to 45O (serial version), as @BrunDog suggested.

10 DS18B20 sensors, but only testing 1 for right now. Wired over XLR. I am currently not using a resistor. I have not reset the 1 wire bus using control codes, but now see how to do that in manual. The only resetting I was doing with the physical reset button on the MEGA, not sure if that's what...

I have this 16 relay board which I plan to use for the valves.

Attached are screenshots of how my brucontrol is configured along with my 1 wire config (using the virtual ports allowed me to add the sensor, thanks @oakbarn ). However I am unable to get any data readings and am not able to get any from the test onboard led on MEGA (I have it configured to pin...

Thanks for this information. So on the hardware side I should run all the data pins in parallel back to a singular arduino pin, potentially #5? How will I be able to separate out the data for 10 different temperature points? and the 5V power needs to have a 4.7k pull down resistor? Any advice...

New to brucontrol and trying to add some 1-wire DS18B20 temp sensors and 9-24V reverse polarity ball valves. So far I have the temp sensors wired, red: 5v, black: gnd, yellow: digital pin 2 on a arduino mega 2560. However, I do not see 1-wire as an option when adding a new device like is shown...
