We want to use a LCD to display the current speed of the wheel.
We managed to display something on the screen.
Here we used a potentiometer to control the contrast of the LCD.
We coded on arduino to let LCD display different texts.
Here is the code we used in the picture above.
#include <LiquidCrystal.h>
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.
lcd.print("Current Speed");
}
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);
lcd.print(" MPH");
}
