The code to read that value is as follows: batVal = analogRead(batMonPin); // read the voltage on the divider pinVoltage = batVal * 0.00488; // Calculate the voltage on the A/D pin // A reading of 1 for the A/D = 0.0048mV ...
The circuit based on a photoresistor uses a resistor divider to allow the high impedence Analog input to measure the voltage. These inputs do not draw almost any current, therefore by Ohm's law the voltage measured on the other end of a resistor connected to 5V is always 5V, regardless ...
映射的0-5V可以从标记为Voltage的中间部分获得。然后可以将该映射电压反馈到Arduino模拟引脚。接下来我们...
PT100有一个标准的阻值温度对应表，在0度的时候，它的电阻值在100R，在常温25℃，它的电阻值是109....

前两天发布的一个用Arduino制作的RC控制器,有朋友留言说对这个项目的制作过感兴趣,所以本期我把制作的详细过程与大家一起分享。 第1部分—发射机原理图 下面是这个项目的示意图,其中包含所有连接和组件值。在下面的完整部件列表中也检查这个项目所需的所有内容。确保你把降压转换器设置为12.6V和3.3V,然后再连接到...
board. It has an LCD with 1602 white characters and a blue backlight. Five keys make up the keypad: select, up, right, down, and left. Only one ADC channel is used by the keypad interface in order to conserve digital IO pins (AD0). A five-stage voltage divider reads the key ...
User Manual Introduction:We spend so much time talking about sensing things less mechanical, that is is easy to forget the accelerometer isn’t the only part in town. The flex sensor is one of those parts often overlooked by the advanced user. But what if you need to check if something ...
For a 20 A type sensor, 100 mV/A would be the normal value. After using a voltage divider one need to adjust the mVperAmp. For a 30 A type sensor, 66 mV/A would be the normal value. After using a voltage divider one need to adjust the mVperAmp. ...
