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...
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 thermocouple. It has an SPI communication...
