arduino 12v

Here is a useful, simple and tested Arduino voltmeter circuit which can safely measure input DC voltages from 0V to 30V, including 12V. Sorry if the answer to this question is completely obvious, I am new to arduino and coding in general. So, the equation

And to accomplish this we’re using an N Channel Mosfet.. ابھی, obviously, the Arduino cannot power the LED strip directly.. First of all, the Arduino can only put out a maximum of 5V. Secondly, it can only draw a small amount of power from each pin., So

Arduino针脚供电最大5V,电流最大40毫安左右。 如果直接接入12V电压,则可能烧毁。 所以,需要把12V电压,转变为Arduino可接受的电压和电流值才行。 所以,需要从电压和电流两方面来做限制。 注:以下数值皆根据欧姆定律计算而出。
