If you want to learn Analog to Digital Converter (ADC) experiments with Arduino, you need to understand some basic concepts and follow these steps:
If you want to learn Arduino's modulus converter (ANALOG-To-Digital Converter (ADC) experiment, you need to learn some basic concepts and follow the steps below:
1. Understanding ADC Concepts
1. Understand the concept of ADC模数转换：将模拟信号（连续的电压信号）转换为数字信号（离散的数值）的过程。 分辨率：ADC能够区分的最小模拟信号变化。 Arduino UNO的ADC分辨率为10位，意味着它可以区分0至1023之间的数值。 参考电压：Arduino UNO的参考电压通常是5V，这意味着ADC的最大输入电压为5V，对应于ADC输出的最大数值1023。 Model conversion: The process of converting analog signals (continuous voltage signals) into digital signals (discrete values). Resolution: ADC can distinguish the minimum analog signal change. Arduino Uno's ADC resolution is 10 bits, which means that it can distinguish the value between 0 and 1023. Reference voltage: The reference voltage of Arduino UNO is usually 5V, which means that the maximum input voltage of ADC is 5V, corresponding to the maximum value of 1023 for ADC output.
2. Prepare experimental materials

Arduino board (such as Arduino Uno), connecting wires, variable resistors (potentiometers) or other simulated sensors, Breadboard (bread board) options, computer and Arduino IDE software.
3. Connect the circuit
3. Connection circuit Connect one end of the potentiometer to the Arduino's GND (ground) and the other end to 5V (power). The middle pin of the potentiometer (usually the middle pin) is connected to one of the analog input pins of the Arduino, such as A0.
Connect one end of the variable resistor to the GND (ground) of Arduino, and the other end to 5V (power). The middle pins of the variable resistor (usually the pins in the middle) are connected to an analog input pin from Arduino, such as A0.
4. Write code
4. Writing code
打开Arduino IDE，编写一个简单的程序来读取模拟引脚的值，并将这些值显示在串行监视器上。 使用`analogRead()`函数来读取模拟引脚的值。 Open Arduino IDE, write a simple program to read the value of the simulation pin, and display these values on the serial monitor. Use the `Analogread ()` function to read the value of the simulation pin.
5. Upload the code
