Hello,
i wanted to do a little program where i can scroll a single character with a potmeter on my LCD.
This is what i have written:
#include <LiquidCrystal.h>
LiquidCrystal lcd(12,11,5,4,3,2);
int potVal;
int prevPotVal = 0;
byte smiley[8] = {
B00000,
B10001,
B00000,
B00000,
B10001,
B01110,
B00000,
};
int pose = 8;
void setup() {
Serial.begin(9600);
lcd.createChar(0,smiley);
lcd.begin(16,2);
}
void loop() {
int potVal = analogRead(A0);
setPose();
if (potVal != prevPotVal) {
lcd.clear();
lcd.setCursor(pose,0);
lcd.write(byte(0));
}
prevPotVal = potVal;
Serial.print("pose:");Serial.print(pose);
Serial.print("potval: "),Serial.println(potVal);
}
void setPose() {
if (potVal < 64) {
pose = 0;
} if (potVal >= 64 && potVal < 128) {
pose = 1;
} if (potVal >= 128 && potVal < 192) {
pose = 2;
} if (potVal >= 192 && potVal < 256) {
pose = 3;
} if (potVal >= 256 && potVal < 320) {
pose = 4;
} if (potVal >= 320 && potVal < 384) {
pose = 5;
} if (potVal >= 384 && potVal <448) {
pose = 6;
} if (potVal >= 448 && potVal < 512) {
pose = 7;
} if (potVal >= 512 && potVal < 576) {
pose = 8;
} if (potVal >= 576 && potVal < 640) {
pose = 9;
} if (potVal >= 640 && potVal < 704) {
pose = 10;
} if (potVal >= 704 && potVal < 768) {
pose = 11;
} if (potVal >= 768 && potVal < 832) {
pose = 12;
} if (potVal >= 832 && potVal < 896) {
pose = 13;
} if (potVal >= 896 && potVal < 960) {
pose = 14;
} if (potVal >= 960 && potVal < 1024) {
pose = 15;
}
}
I monitored the value of “pose”, and it always puts out 0, no matter what, so for some reason the first if statement is always true, and i dont know why.
please help
