您现在拥有一款适用于Arduino板的简单易用LCD显示屏,并可将其用作未来项目的显示屏。提示:I2C是一个慢速总线,如果您持续更新液晶显示器,那么会影响单片机执行其他任务的时间。 图6:LCD显示 “Test” 图7:LCD显示程序运行时间 – 8(s) 图8:LCD显示程序运行时间 – 28(s) 附件:Arduino_LED代码 /* Project: A...
When running your “Getting the LCD Address” code in arduino uno, the program says that the lcd is in address 0x3C, but I have it running in address 0x27. In the esp32… The LCD receives the proper 5V. Connections are double checked. Installed the library as (you) suggested. My int...
//Before uploading the code to the Arduino, disconnect the Tx and Rx pins, otherwise you won‘t be able to upload. Once the code uploaded, reconnect them. 现在打开BlueTerm,打开蓝牙并连接HC-05。然后只需输入您的文本,它就应该在LCD上打印!

Using an LCD is one of the ways to output information in Arduino projects. The main drawback about an LCD is that it occupies too many pins on your Arduino board. But there are some serial implementations such ashere. So I got one. ...
A how-to on using an I2C LCD display with the ESP32 using Arduino IDE from Random Nerd Tutorials: This tutorial shows how to use the I2C LCD (Liquid Crystal Display) with the ESP32 using Arduino IDE. We’ll show you how to wire the display, install the library and try sample code ...
The arduino code listens for any strings coming in through the serial port, removes the first two characters which I chose to be the position where to write the string on the LCD and the rest would be the string to output. String Format:##String(since this is a16x2LCD the first number...
