Reads an analog input and prints the voltage to the Serial Monitor. 读取模拟输入并打印电压值到串口监视器。 This example shows you how to read an analog input on analog pin 0, convert the values from analogRead() into voltage, and print it out to the serial monitor of the Arduino Software...
If the button is not pressed, Arduino will detect 1.You can also use the constants LOW, which maps to 0, and HIGH that maps to 1.This value can be printed to the serial output, like in this program:#define BUTTON_PIN 3 void setup() { pinMode(BUTTON_PIN, INPUT_PULLUP); Serial....

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"。
Solved: Hello, I am using an Arduino UNO with the TLE9879 BLDC Shield (TLE9879QXA40). I was successful in flashing and getting it to work initially,
MODBUS RTU MASTER READ INPUT REGISTERS In order to set an M-Duino as a master and the other one as a slave, we will have to program both to execute each code. So, in order to program the master, open up a new file of Arduino IDE, and paste the code below:...

it can also be used as an input device that takes input from a user and sends it to the Arduino. This is useful for creating serial monitor based menus, calculators, and password logins, where the user is asked to input information and the Arduino performs an action based on that input....
