Arduino Mega2560的设计与Arduino USB接口标准版的设计完全兼容,因此用于Arduino UNO和之前系列的扩展板也可以用在Arduino Mega2560上。 扩展阅读 附件:ATmega2560-Arduino 引脚图 Below is the pin mapping for the Atmega2560. The chip used in Arduino 2560. There are pin mappings toAtmega8andAtmega 168/328as...
When the pin is HIGH value, the LED is on, when the pin is LOW, it's off. TWI: A4 or SDA pin and A5 or SCL pin. Support TWI communication using the Wire library. The Uno has 6 analog inputs, labeled A0 through A5, each of which provide 10 bits of resolution (i.e. 1024 ...

The Uno has 6 analog inputs, labeled A0 through A5, each of which provide 10 bits of resolution (i.e. 1024 different values). By default they measure from ground to 5 volts, though is it possible to change the upper end of their range using the AREF pin and the analogReference() fun...

- Arduino board (Uno, Mega, Duemilanove, etc.) Instructions: --- If this is your first Arduino project, first go through our “Arduino: Getting Started” tutorial. --- To obtain the unique serial number of your 1-Wire devices, follow this procedure for each device, one at a time. Use...
DS3231 uses SDA (Data Pin) and SCL (Clock Pin) only because of the I2C protocol. This module is designed to communicate using the I2C protocol. So, at first, find the SDA and SCL pin of your Arduino uno or compatible board. If you are using Arduino uno board pin A4 and A5 is SDA...
