![]() The analog voltmeter VI is a modified version of the tutorials provided by LabVIEW MakerHub. The next development phase of the project is to communicate with the LabVIEW analog voltmeter VI. If not, repeat this step again.Ĭlick Launch Example and follow the instructions on the front panel. Note: The TX (transmit) and RX(receive) LEDs on your Arduino Uno should be on for a few seconds while the firmware is being installed. Select the Firmware Version (start with the Serial/USB firmware) and click Next.Select the COM Port associated with your device and click Next.Click Tools> MakerHub>LINX> Firmware Wizard.Attach the Arduino Uno to your desktop PC or notebook using a USB cable.For this project, the Arduino Uno is used. To complete the final installation phase of the LINX project task, the following steps will assist in loading the firmware to your target embedded control development platform. The LabVIEW MakerHub LINX add on software package allows direct communication and control of the embedded control development platforms’ I/O (input/output) pins interfaced to electronic circuits, sensors, and electromechanical actuators. Install the add-on software package following the installation prompts. Download the LINX add-on software to your development machine’s hard-drive. Also, analog, digital, and PWM (pulse width modulation) signals can easily be controlled using the LabVIEW VI based software as well. The LINX firmware allows communication between the interfacing components and the embedded control development platforms to communicate using USB, I2C (inter-integrated circuit), and SPI (serial peripheral interface) protocols. The LINX add-on package allows a variety of embedded control development platforms like the Arduino Uno, Diligent's chipkit and NI myRIO to interface with electronic circuits, electromechanical components, and sensors easily using LabVIEW software. After the software has been installed on your target machine, the next project task is to include the LINX add on package. Install the software to your desktop PC or notebook book computer following the installation prompts. There are several software options to choose from, which is convenient from a project development cost view point. The MakerHub website to obtain LabView software for building an analog voltmeter The first step in making the analog voltmeter is to download the LabView software. By placing controls on a user-form and wiring a block diagram with embedded functions, you can easily build a graphical user interface (GUI) for controlling electronics and robotics devices. National Instruments (NI) LabView software allows a variety of virtual instruments (VI), electronic controllers, and robotics devices to be built using a graphical programming language. After following the project build instructions, the analog voltmeter will be checked against a digital voltmeter for measurement accuracy using a littleBits slide dimmer control circuit. The concept behind this project is to show how a simple analog voltmeter can be built using an Arduino, several littleBits electronic modules, LabView, and LINX software packages. The multimeter is designed with analog meters or liquid crystal displays (LCDs) for displaying voltage, current, and resistance electric circuits values. The multimeter is a basic electrical instrument used to measure electric circuit parameters such as voltage, current, and resistance. ![]() ![]() The first electrical instrument introduced to ILT students is the multimeter. The idea behind teaching this topic is to introduce basic electrical instruments technology and measuring practices to Industrial Electrical-Electronics technology (ILT) students. The values 200 and 40 were found by testing, all I did was move the joystick one way and the other several times to see what values they produced, then I choose values (200 and 40) that will be sure to include these values.Electrical testing and measurements is a fundamental topic taught in a community college DC electronics course. Note that if you remove the Serial.print line, for some reason, the motor will not turn. Serial.print("joy X: ") Serial.println(nunchuck_joyx()) Please note that the motor am using here is a full rotational model so when I use the servo library the angles get translated to speed and direction, 90 degrees is zero speed, 0 degrees is full speed right, 180 is full speed right. What we want to do is turn the motor left if you move the chuck’s joystick all the way to the left and turn it right if you move it to the right. You’ll need the wiichuck library for this, download it and paste in your "libraries" folder in your Arduino directory.
