一旦你知道开发板的IP地址,你可以在一个Web浏览器里打开该地址来打开和关闭引脚9上的LED。 如果你的扩展块/板的IP地址是你的地址: http://yourAddress/H打开LED http://yourAddress/L关闭LED 这个例子是为一个使用WPA加密的网络编写的。对于WEP或WPA,相应地改变Wifi.begin()的调用。 硬件要求 Arduino WiFi Sh...
芯片出厂时在这个区域预置了一段Bootloader,就是通常说的ISP程序。这个区域的内容在芯片出厂后没有人能够修改或擦除,即它是一个ROM区,正是因为有这个区的存在,STM32(包括arduino)才能够支持ISP烧录 在每个STM32的芯片上都有两个管脚BOOT0和BOOT1,这两个管脚在芯片复位时的电平状态决定了芯片复位后从哪个区域开始...

Instead, have a look at Blink without delay and AvoidDelay on the Arduino site for more. Avoid using it from inside interrupts By "it" I mean this library. ISR / Interrupts stops most other things in the micro-controller (Arduino), including the timer counter obtainable from the millis()...
You can't see the light from the LED so it's a bit difficult to test the circuit. If you want to make absolutely sure that the LED is working, try writing a quick Arduino sketch to blink the LED pin on and off, then pointing a digital camera at the LED- the camera will pick up...
There are a couple LEDs on this board, labeledTXandRX, which will blink when data transfers from your computer to Arduino, or vice-versa. Look for them to blink like crazy when you upload code to the board. Lithium Polymer (LiPo) Battery ...
For the electronics, I've used an Attiny85 microcontroller that runs a simple random blink sketch to turn on the LEDs with random durations as well as random off times. The LEDs are salvaged from a 12V 5050 LED strip and I've added a relatively small resistor so they can be powered fro...
This connects to a network and allows you to blink an LED on some versions of the ESP32 boards. Mine, however, does not have this LED. My thought around this was to combine the 2 examples together. (both ran perfect separate) I took my tft.pushImage(0, 0, 240, 240, epd_bitmap...
After assembling the board, it was time to start on the software. I wrote the software in three phases. The first phase was getting a timed main loop running that would blink a heartbeat LED periodically. The second phase was writing the interrupt driven code to receive and decode the Wieg...
