Hi, I'm newbie to arduino, does anyone know how to add smooth range bargraph meter on the second line with 2x16 LCD to that code?
LiquidCrystal lcd(8, 9, 4, 5, 6, 7); int pingPin = 13; int inPin = 12;
void setup() { lcd.begin(16, 2); lcd.print("testing..."); }
void loop() {
long duration, inches, cm; pinMode(pingPin, OUTPUT); digitalWrite(pingPin, LOW); delayMicroseconds(2); digitalWrite(pingPin, HIGH); delayMicroseconds(10); digitalWrite(pingPin, LOW);
pinMode(inPin, INPUT); duration = pulseIn(inPin, HIGH);
inches = microsecondsToInches(duration); cm = microsecondsToCentimeters(duration); lcd.clear(); lcd.setCursor(0, 0); lcd.print(inches); lcd.print("in, "); lcd.print(cm); lcd.print("cm");
delay(100); }
long microsecondsToInches(long microseconds) {
return microseconds / 74 / 2; }
long microsecondsToCentimeters(long microseconds) { return microseconds / 29 / 2; }
Many thanks for any suggestions.
