This tutorial uses an LCD to show someone's name on the screen. This project is based on TinkerCAD LCD sample code.
本文使用 LCD 來顯示英文姓名。此範例是修改 TinkerCAD Circuits 的內建範例。
材料(Materials)：
1. Arduino UNO R3 板子 x 1
2. 可變電阻 Potentiometer x 1
3. 16 x 2 LCD 模組 x 1
4. 杜邦線 jumper wire x 22
5. 麵包板 small breadboard x 1
6. 220歐姆電阻 220 ohm resistor x 2
電路(Circuit)：
程式碼(The Code)：
// include the library code:
#include <LiquidCrystal.h>
// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
void setup() {
// set up the LCD's number of columns and rows:
lcd.begin(16, 2);
// Print a message to the LCD.
// **** Your english name here ****
lcd.print("Holan");
}
void loop() {
// set the cursor to column 0, line 1
// (note: line 1 is the second row, since counting begins with 0):
lcd.setCursor(0, 1);
// print the number of seconds since reset:
lcd.print(millis() / 1000);
}
