but the same code and concepts work for other Arduino development boards also. Firstly,16×2 LCDinterfacing with Arduino will be discussed. After that, we will also provide examples of 16×4 LCD and I2C LCD interfacing with Arduino.
With the example code below, you can display the temperature readings on a 16×2 character I2C LCD. Connecting the I2C LCD is very easy as you can see in the wiring diagram below. You can check out my detailed tutorial below for more information.How to control a character I2C LCD with ...

If you need more EEPROM storage than what is available with your microcontroller, consider using an external I2C EEPROM as described in the Arduino and I2C tutorialpart two. At this point we now understand what sort of data and how much can be stored in our Arduino’s EEPROM. Now it is ...
1.使用的LCD1602必须先焊接到LCD1602 I2C模块 2.I2C模块的SDA(串行数据)和SCL(串行时钟)不可以随便乱接。对于Arduino Uno来说,SDA必须接A4,SCL必须接A5 尽管有这些限制,但无疑,它的确在很大程度上减少了芯片之间的连线。 使用I2C需要遵循I2C协议。一般在Arduino中,通过导入LiquidCrystal_I2C库来完成控制。由于笔者手...

similar tohow I controlled a salvaged I2C LCD. But this exploration was much easier because a user on FormLabs forumsrecognized the SSD1305-based display module. Thanks to that information, I had a datasheet todecipher the commands, and I could go searching to see if anyone has written code...
The use of the I2C LCD display is optional but makes understanding the process easier. This uses three LEDs on DP9, DP10, DP11. Two normally open push button switches are connected to DP2 and DP3 to ground. Internal pull ups are used - switch closed reads as false or 0. Instead of ...
使用HC-05将数据从Arduino发送到手机是一种通过蓝牙通信实现的方式。HC-05是一种常用的蓝牙模块,可以将Arduino与其他设备(如手机)进行无线通信。 具体步骤如下: 硬件准备:将HC-05蓝牙模块与Arduino连接。将HC-05的VCC引脚连接到Arduino的5V引脚,GND引脚连接到Arduino的GND引脚,TX引脚连接到Arduino的RX引脚,RX引脚连接...
