但如果您有 16x2 LCD 和 I2C 模块,请参阅将此模块连接到 LCD 的步骤。 联系 首先焊接 I2C 模块。I2C 模块上没有用于连接 16x2 LCD 的标签。所以在下面给出的图像的帮助下焊接它 16x2 LCD 上的 I2C 模块 焊接后将 I2C 模块连接到 Arduino Uno。 Arduino Uno I2C 模块 模拟引脚 4 - SDA 模拟引脚 5 ...
In this instructable I will show you how I connected a serial LCD 16X2 to an Arduino UNO. There are lots of instructables and tutorials showing you how to connect a regular LCD to an Arduino but not many showing a serial LCD and on my Arduino the PINS to attach the UART pins are hid...

lcd.print(“S2: 0”); } 将Arduino UNO测试为RS485 MODBUS主设备 在电路连接完成并将代码上传到Arduino Uno之后,现在是时候将USB连接到RS-485模块了 注意:打开设备管理器,并根据连接了USB到RS-485模块的PC并检查COM端口。然后打开Modbus Slave软件。 1。Modbus Slave Tool出现如下,指示 No Connection。 2。下...
● 1602 LCD显示屏 ● Modbus Slave 电路原理图 MAX-485 TTL至RS-485转换器模块与Arduino UNO之间的电路连接: 带有10k下拉电阻的两个按钮也连接到Arduino引脚4和5。10K电位器用于为Arduino引脚A0提供模拟输入值。 电路连接后,完整设置如下所示。 编程Arduino Uno作为MODBUS Master ...
In this repository I've uploaded different "games" coded in C++ thought to be run in a 16x2 LCD using an arduino board. I tryed to imitate those 80's pocket computers that were able to run games coded in BASIC in a little LCD screen, with the difference of using the arduino C++ in...

Unfortunately, these LCDs do require quite a few digital pins, 6 to control the LCD and then another pin to control the backlight for a total of 7 pins. That's almost half of the pins available on a classic Arduino! With this in... Add to Cart, LCD Shield Kit w/ 16x2 Character...
