当电第一次被发现时,人们认为它是从正极到负极移动的,所以按照惯例,电子电路通常是从正极到负极,从正极到地(GND)。在本书的电路中,电流将向一个方向流动;这被称为直流电(DC),而在交流电(AC)中,方向每秒钟改变一定次数。 为了让导电材料中的电子开始移动,它们需要一个推力,这个推力就是电压。电压是电路中较高...

PART 2K-Thermocouple temperature read So, let’s start building this project. The first thing we will do, is see how to read the real temperature. Below we can see a K type thermocouple, and the MAX 66 75 breakout module. This will amplify and compensate the voltage created by the therm...
Arduino MCP4725数字模拟转换器用户手册说明书 User Manual MCP4725 Pin Outs The VCC connects the chip VDD pin. What’s important to understand is that this does not supply power to the chip, but it acts as the reference voltage as well.
VIN.The input voltage to the Arduino board when it's using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin. ...
