LED 13: It is an inbuild LED in the Arduino boards similar to that in Arduino Uno and mega. The LED is high when this pin is provided with a high signal. AREF: It is the reference voltage pin and is used with the function analog reference () in analog inputs. RESET: The reset ...
The Arduino Mega 2560 is a replacement of the old Arduino Mega, and so in general reference, it will be called without the ‘2560’ extension. Due to the many numbers of pins, it is not usually used for common projects but you can find them in much more complex ones likeRadon detectors...
AREF模拟输入口参考电压 AREF stands for Analog Reference Voltage which is a reference voltage for analog inputs. Analog Pins 16个模拟量输入引脚(10位的分辨率,对应于0-1024) There are 16 analog pins incorporated on the board labeled as A0 to A15. It is important to note that all these analog ...

TheSCLconnection goes to Arduino pinA4. TheSCLconnection goes toA5. If your Arduino Uno has a separate set of SDA and SCK connections (usually located near theAREFpin) you can use those instead, they are actually the same connection. ...
The Arduino has just enough IO to implement the entire HV protocol plus a “go” button. So far I have only implemented setting LFUSE and HFUSE in software, but there is no reason why the code couldn’t be extended to support chip erase and programming the entire flash as well. ...
