The Arduino boards have a circuit inside called ananalog-to-digital converter or ADCthat reads this changing voltage and converts it to a number between 0 and 1023. When the shaft is turned all the way in one direction, there are 0 volts going to the pin, and the input value is 0. ...

37款传感器与执行器的提法,在网络上广泛流传,其实Arduino能够兼容的传感器模块肯定是不止这37种的。鉴于本人手头积累了一些传感器和执行器模块,依照实践出真知(一定要动手做)的理念,以学习和交流为目的,这里准备逐一动手尝试系列实验,不管成功(程序走通)与否,都会记录下来—小小的进步或是搞不掂的问题,希望能够抛砖引...
In the node configuration, select the Arduino pin that corresponds to the input of the PLC controller, and replace the A0 port with D + the one of your Programmable Logic Controller. For example: In our case, we are using an M-Duino 21+ industrial PLC. If we want to test the I0.12...

我想通过 SPI 阅读具有 Arduino 的 ADS131E04。 遗憾的是、我以前没有什么经验、这是我第一个使用 SPI 通信的项目。 SPI 的电压电平为3.3V、应与 ADC 配合使用。 我将 SPI 通信的时钟速率设置为4MHz。 SPI 模式为1 (CPOL = 0、CPHA = 1)、我已设置"MSB 优先"。
```cpp include <arduino.h> define SPI_CLOCK 5 // 时钟线 define SPI_MOSI 6 // 主机输出,从机输入 define SPI_MISO 7 // 主机输入,从机输出 define SPI_CS 8 // 片选信号 // 函数声明 void writeSPI(uint8_t data);uint8_t readSPI();void setup() { pinMode(SPI_CLOCK,...
