一、实验目的 本次实验的目的是利用热敏电阻和LabVIEW中的热敏电阻函数节点,通过Arduino Uno控制板的模拟端口采集与热敏电阻串联电阻的分压值,并将该值上传给LabVIEW软件。随后,软件将对该值进行处理,除以温度系数以获得温度值,从而实现一个温度计的功能。最后,我们将断开与Arduino Uno控制板的连接,以便读者
如下图所示: 2、LabVIEW LINX Toolkit的基本使用 下载完成后,打开LabVIEW,选择:工具→MakerHub→LINX→Linx fireware Wizard,如下图所示...: 在跳出的界面中选择好自己的板子及型号,我这里是Arduino Uno,如下图所示: 点击Next,选择本次连接上Arduino串口(注意,此时你的Arduino已经连接了电脑而且串口被识别了,可以...
The diagram shows that various information like flame, smoke, temperature, and obstacle objects in and around the fire accident zone is sensed by the flame sensor, smoke sensor, temperature sensor, and ultrasonic sensor, respectively. The sensed signals are sent as inputs to Arduino Uno, which ...
The Arduino UNO R4 Minima (from here on referred to as UNO R4 Minima) is the first UNO board to feature a 32-bit microcontroller. It features a RA4M1 series microcontroller from Renesas (R7FA4M1AB3CFM#AA0), which embeds a 48 MHz Arm® Cortex®-M4 microprocessor. The UNO R4's...
There are six pins on the Arduino Uno (shown below A0 ~ A5) that can be selected for an ADC measurement; A multiplexor feeds one of the six analogue input pins into the ADC. Use the function: analogRead(pin) Setting of the multiplexer is done in that function for you automatically. ...
Uno R3 Like the Uno R2 and Uno SMD, the Uno R3 utilizes a second microcontroller to handle USB communications. The Arduino Ethernet does not have built-in USB. Figure 4-15 shows the block diagram for the Uno R3 and Uno SMD boards. The pin functions for the Uno R3 are shown in Figure...
In order to use the Arduino Uno device with LabVIEW, you need the LINX toolkit. This toolkit is automatically installed with LabVIEW Community Edition. You may be prompted to restart. Return to topActivate and Register Step 2. After the installation is complete, the Activation Wizard opens ...
Typically used to add a reset button to shields which block the one on the board. Communication The Arduino Uno has a number of facilities for communicating with a computer, another Arduino board, or other microcontrollers. The ATmega328 provides UART TTL (5V) serial communication, which is ...
An Arduino Uno 微控制器具有中央处理单元(CPU);它存储上传的草图,并处理和指导命令。 数字和模拟引脚用于发送和接收数字和模拟数据。 Arduino 还有一个串行接口,允许 Arduino 通过串行端口向计算机发送数据;这就是我们在本书中向计算机发送数据和从计算机接收数据的方式。
