In the previous tutorial, we learned to blink LED by using the delay method. That method blocks Arduino from doing other tasks. In this tutorial, we are going to learn another method to blink LED without blocking other tasks. The detail instruction, code

This is the DS3231 Precision RTC FeatherWing: it adds an extremely accurate I2C-integrated Real Time Clock (RTC) with a Temperature Compensated Crystal Oscillator (TCXO) to any Feather main board. This RTC is the most precise you can get in a small, low power package. Using our Feather ...

在控制LED之前,您可以使用电路根据电位器的位置检查Arduino读取的不同值。为此,请在您的PC上运行以下程序: Python import pyfirmata import time board = pyfirmata.Arduino('/dev/ttyACM0') it = pyfirmata.util.Iterator(board) it.start() analog_input = board.get_pin('a:0:i') ...
第一个是Arduino Sketch,第二个则是运行在你服务器上的PHP脚本和来自Arduino的HTTP Get请求。ESP8266上使用的HTTP 1.0协议有些过时,用起来有些不舒服,你只能通过它发送HTTP Get请求和HTTP Post请求。所以你需要将来自Arduino的HTTP Get请求转换成STMP(简单电子邮件协议)或其他格式,而这正是PHP脚本的一部分。
