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
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...
however, the 5V pin may supply less than five volts and the board may become unstable. If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range is 7 to 12 volts.
Arduino Uno ADC resolution As we saw earlier the resolution of the ADC, when Vref=5V is 4.88mV per step. The Arduino analogRead resolution which is the same as the resolution of the ADC is governed by two things The ADC size - 10bits for the Uno. The ADC reference voltage - You can...

I connected a small LED to pin 11 to see the results of the above PWM code sample. As expected, it operates at a reduced brightness due to the lower voltage. The ‘127’ is a number that can range from 0 to 255, with 255 being the brightest setting. You can use this to set the...
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...
