begin(16, 2); scrollText("This is a scrolling text!"); } void loop() { // 空循环,滚动显示功能在scrollText函数中实现 } void scrollText(String text) { int textLength = text.length(); for (int i = 0; i < textLength + 16; i++) { // 加16是为了确保文字完全滚动过去 lcd....
As expected above code displays “ABC”. The lcd.print() function is used to send data. The most important thing to consider in this code is the position of the displayed text. As you can see from the figure, it starts printing text from the first location of LCD that is the first r...
与其他产品相比,OLED的质量比较小,厚度与LCD相比是比较小的,其抗震系数较高,能够适应较大的加速度,振动等比较恶劣的环境。 OLED优势 相比传统的LCD技术,OLED显示技术具有明显的优势,OLED屏幕厚度可以控制在1mm以内,而LCD屏幕厚度通常在3mm左右,并且重量更加轻盈。OLED屏幕的液态结构可以保证屏幕的抗衰性能,并且具有LCD不...

When you want to print a message on a dot matrix display, you will often find that the display is too small to fit the entire message. The solution is in the MD_Parola library, which makes it super easy to create scrolling text effects. In the following examples, I will show you how...
// draw scrolling text testscrolltext(); delay(2000); display.clearDisplay(); // text display tests display.setTextSize(1); display.setTextColor(WHITE); display.setCursor(0,0); display.println("Hello, world!"); display.setTextColor(BLACK, WHITE);// 'inverted' text ...
焊接到LCD显示屏引脚的排针 10k ohm 电位计 220 ohm 电阻 连接线 面包板 电路 在连接液晶显示屏到你的Arduino板之前,我们建议到焊接一组排针到LCD显示屏的连接器上(14或者16引脚数),你在上面的图可以看到。 液晶显示屏连接到电线板,连接引脚: LCD RS pin to digital pin 12 ...

LED matrix displays take dot matrix displays a step further by allowing you to control individual LEDs, making them perfect for scrolling text, animations, and graphics. Nextion displays come with a built-in touch interface, making them ideal for creating interactive projects with graphical user int...
