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...
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,...
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 ‘duty cycle’, which is explained in the PWM article I linked to above....

有个神奇的地方,ESP的芯片有专门控制LED的外设,又因为控制LED就是控制的PWM,舵机的控制也是PWM,所以很自然的就会想到用LED的外设去控制舵机。 可以参考官方的文档 LED 控制 (LEDC) 外设主要用于控制 LED 的强度,但也可用于生成 PWM 信号以用于其他目的。它有 16 个通道,可以生成独立的波形,例如用于驱动 RGB LED...

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...
