模块接线方式也很简单,直接安装到 1602 上: 此时,将SDA、SCL、VCC、GND 连接到 Arduino 上,就能实现通信。是不是非常清爽?另外,电位器的作用是调节字体对比度。 Arduino-LiquidCrystal-I2C-library-master库 ,导入到 IDE 里面后,写入第一个程序: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19...

where the lower of the two system voltages exceeds the high-level input voltage of the the higher voltage system--for example, a 5V Arduino and a 3.3V accelerometer. Depending on the design of the Arduino or the I2C device, we recommend using a logic level converter to be consistent and ...
Please, before reporting any issue I am using the latest Arduino STM32 Core, as of writing this. My particular problem has not been reported before. It is definitely a problem related to Arduino STM32 Core. When reporting any issue, plea...
The MCP4725 is an I2C controlled Digital-to-Analog converter (DAC). A DAC allows you to send analog signal, such as a sine wave, from a digital source, such as the I2C interface on the Arduino microcontroller. Digital to analog converters are great for sound generation, musical instruments...
