首先,将Arduino Uno的5V和GND引脚连接到面包板电源轨,并将LCD插入面包板。 现在,我们将打开LCD的电源。LCD具有两个独立的电源连接;一个(引脚1和2引脚)用于LCD本身,另一个(引脚15和16引脚)用于LCD背光。将LCD上的引脚1和16连接到GND,LCD上的引脚2和15连接到5V。 绝大多数LCD都具有用于LED背光的内置串联电阻。...

将Arduino Uno连接到I2C LCD显示器 连接I2C LCD比连接标准LCD容易得多。您只需要连接4针而不是12针即可。首先将VIN引脚连接到Arduino的5V输出,然后将GND接地。 现在,我们只剩下用于I2C通信的引脚了。请注意,每个Arduino开发板都有不同的I2C引脚,应相应地连接它们。在具有R3布局的Arduino板上,SDA(数据线)和SCL(...
Now upload the next code to the Arduino UNO/NANO. This code will just read the SPI data from the module using a function called "readThermocouple" and that gives us the real temperature. We print the value on the LCD screen. Have in mind that if you don't have theLiquidCrystal_I2Clibr...
The massively popular Arduino Uno board is the perfect board to start any budding electronics engineer. With this board you have endless possibilities from the simple LED blinking to energy monitoring to controlling unmanned vehicles. The Arduino Uno mic
For example: The Arduino Uno used in this tutorial is a kit that has an Atmel ATmega 328P microcontroller (MCU). It is an 8-bit MCU with a 16MHZ RISC processor and 32KB of built-in flash memory.The microcontroller itself (the ATmega 328P) is a tiny chip plugged into the Arduino ...
PREVIOUS TUTORIAL NEXT TUTORIAL Drawing bitmap images (.BMP format) on ST7735 TFT display is quite easy because they are uncompressed images unlike JPEG images (.JPG format). This post shows how to draw bitmap images on the ST7735 TFT using Arduino UNO board where the Arduino loads the ...
