When the push button is pressed, the Arduino will send a notification to the Raspberry Pi (a simple byte). The Raspberry Pi will then compute a random integer number between 1 and 4, and send it to the Arduino. The Arduino will power on the LED related to this number, and power off...
Serial.print(数据,数据的进制)如果没有指定,预设以一般文字传送。 范例: Serial.print(75); // 列印出 "75" Serial.print(75, DEC); //列印出 "75" Serial.print(75, HEX); // "4B" (75 的十六进位) Serial.print(75, OCT); // "113" (75 in的八进位) Serial.print(75, BIN); // "100...
一、硬件设备：1、esp32 esp32 2、tft屏幕1.8寸 （不带触摸屏） tft屏幕（1.8寸）注意该款tft芯片st7735（不懂驱动芯片的内存可以咨询卖家） 在TFT_eSPI设置中需要 tft屏幕主要参数列表 3、杜邦线（双头母） 6~7根 二、连接屏幕 （这里连接GPIO脚可以配合后面下一步设置看，为了方面这里直接连接TFT_eSPI...

In this Arduino Serial example, we will write text to the Arduino serial port, which will send it over the USB cable to your computer, which will then display that text in a terminal window. In the ‘setup()’ function mentioned above, add the following lines to start the Arduino serial...
Send and Receive Data Between Arduino and Host Using Serial Communication Send and Receive Data of Variable Lengths Using Arduino Serial Communication Blocks Use Serial Communication with Arduino Hardware External Websites https://reference.arduino.cc/reference/en/language/functions/communication/serial/ ...
Serial communications provide an easy and flexible way for your Arduino board to interact with your computer and other devices. This chapter explains how to send and receive information using this capability. Chapter 1 described how to connect the Arduino USB serial port to your computer to upload...
