Hello this is my code in Tinkercad. I created schema for Bargraph with LED. Two LED (Yellow and Orange) not work correctly.
My code is below:
int sensorValue = 0;
int outputValue = 0;
void setup()
{
pinMode(A0, INPUT);
pinMode(1, OUTPUT);
pinMode(2, OUTPUT);
pinMode(3, OUTPUT);
}
void loop()
{
sensorValue = analogRead(A0);
outputValue = map(sensorValue, 0, 1023, 0, 100);
if (outputValue > 11) {
digitalWrite(3, HIGH);
} else {
digitalWrite(3, LOW);
}
if (outputValue > 51) {
digitalWrite(2, HIGH);
} else {
digitalWrite(2, LOW);
}
if (outputValue > 91) {
digitalWrite(1, HIGH);
} else {
digitalWrite(1, LOW);
}
delay(2);
}
Not really an SO question since the issue is not with the code, but that is not perhaps for you to know so:
to connect the cathodes to GND.
