If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range is 7 to 12 volts. The power pins are as follows: 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...
arduino leonnardo和uno 这两个板子的CPU不一样,Leonnardo用的是ATmega32u4,UNO用的是ATmega328。最大的区别是在USB上面,Leonnardo的USB接口是CPU原生的,而UNO是通过ATmega16u2转的。这导致它们在使用上有一点微小的区别。Leonnardo可以模拟成USB的键盘,鼠标,而UNO不行。如果使用串口功能,由于Leonardo是CPU直接连接USB,...
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...

37款传感器与执行器的提法,在网络上广泛流传,其实Arduino能够兼容的传感器模块肯定是不止这37种的。鉴于本人手头积累了一些传感器和执行器模块,依照实践出真知(一定要动手做)的理念,以学习和交流为目的,这里准备逐一动手尝试系列实验,不管成功(程序走通)与否,都会记录下来—小小的进步或是搞不掂的问题,希望能够抛砖引...
connected to the a common output - their inputs are also connected. These act as current source and sinks - to allow a large fan out. In normal use the logic driving these inputs is logic high or low. If you drive them at the mid range voltage (think analogue input at Vcc/s) then...
