你把输入值匹配到输出的范围,在这里就是10个LED灯。然后你设置一个循环重复这些输出。如果输出的数字比匹配输入范围要低时,打开LED灯。否则,关闭LED灯。 /* LED bar graph Turns on a series of LEDs based on the value of an analog sensor. This is a simple way to make a bar graph display. Though...
I've been working on an Arduino based smartwatch that could show time, date, alarm, temperature, connect to a smartphone via Bluetooth and show notifications. I had some errors on this baord, but in this tutorial, I'm sharing the good board that I've already fixed. See below all the ...

In this tutorial, we will not try to control any large appliances for the sake of simplicity. We will stick to LEDs that you can connect directly to the Arduino. Just pretend that the LED is an appliance!The first step: Install The Arduino IDE: The Arduino IDE is an app that you can...

At the 2013 Open Hardware Summit, all attendees were given a hackable, ePaper badge (lovingly called a “BADGEr”) that could be used to display our credentials during the conference, and could be used for experimentation afterwards. I paired mine with a Raspberry Pi to create an auto-updati...
我们首先创建一个名为ledPin的整数变量,并给它指定数字 13。给变量起一个有意义的名字是一个好习惯,即使程序很短,只有一个变量。void setup() { 然后我们创建了一个名为setup()的函数。这个函数和loop()函数存在于每个 Arduino 草图中。setup功能是你放置预备代码的地方,比如打开串口,或者,正如我们在这个草图中...
