第三步:Arduino 嵌入式代码编写 过程本人踩过的坑:1.要了解继电器的GPIO用是哪个,不然你无法控制;2.Wifi控制的情况下,由于继电器是有一个虚拟WiFi的,你需要链接到继电器的虚拟WiFi后,才能配置自家的WiFi;当然你也可以连接蓝牙来配置;3.需要把设置好的WiFi账号密码记录到继电器否则每次启动都要配置WiFi(代码写入即可)...

The processor has plenty of GPIO, Analog inputs, hardware UART SPI and I2C, timers and PWM galore - just enough for most simple projects. When we need to go small, we use a Metro Mini or a Trinket M0, but when size isn't as much of a concern, we reach for an Adafruit METRO. ...
Arduino Nano Every has a built-in LED at pin D13 of the board. This pin also serves as an SPI Clock (SCK) and a general-purpose I/O (GPIO) pin. 2.2. Digital I/O Pins Arduino Nano Every contains 22 digital I/O pins. Among these, there are five PWM pins. The description of ea...
