LabVIEW Arduino Projects for Industrial Applications

• The connection between an Arduino board and LabVIEW:

First of all, you are going to look for the sketch called LIFA_Base following the steps in the first screenshot: Este equipo -- Disco local(C:) (or the letter that your local disc has) -- Archivos de programa (x86) -- National Instruments -- LabVIEW 2019 (or the version that you downloaded) -- vi.lib -- LabVIEW Interface for Arduino -- Firmware -- LIFA_Base. Once you found it click on it and an Arduino IDE window is going to pop up on your computer.

After this, go to this window and click Tools (Herramientas) -- Board (Placa) + Processor (Procesador) + Port (Puerto) and select your Arduino board and processor type and the serial port where it is located.

Build the following electrical circuit:

• The Leds can have any color. (The long leg of the leds is the positive part, which has to be connected to its resistor and the other one has to be connected to the ground pin, GND).

• The connections can be done in any of the PWM or DIGITAL pins, except the PWM 0, 1 (RX and TX communication pins), or the 13 (associated with the led of the Arduino board).

• The resistors should be 220 Ohm.

The next step is going to be finding some LabVIEW examples to work with them. Go to Este equipo -- Disco local(C:) (or the letter that your local disc has) -- Archivos de programa (x86) -- National Instruments -- LabVIEW 2019 (or the version that you downloaded) -- Examples -- MakerHub -- LINX. Click on LINX - Blink (Simple). It is a digital output test.

Click on the green button and you will see that the board leds RX and TX are going to light up. This means that the connection between LabVIEW and your board and between your board and LabVIEW MakerHub are working.

If one or both of the leds do not light up, it means that the connection is not working, so disconnect the board from your computer and upload the LIFA_base and the LINX - Blink (Simple) again until it works.

Once it is connected, click again on the green button and the led of the Digital Output Channel is going to light up. Change the number of the channel to try all of your leds. You can also try it with the Arduino board led writing the number 13.

The next test is going to be an Analog input test. The electrical circuit will be the following one:

• Put a potentiometer in your protoboard (better if it is from 0 to 5 analog Voltage).

• The connections will be done as in the picture. (Middle leg to the analog input A0, positive leg to the 5V power pin and negative leg to the ground, GND.

The next step is going to be the same as before. Go to Este equipo -- Disco local(C:) (or the letter that your local disc has) -- Archivos de programa (x86) -- National Instruments -- LabVIEW 2019 (or the version that you downloaded) -- Examples -- MakerHub -- Labview Arduino linx LINX. Click on LINX - Analog Read 1 Channel.
