Potentiometer with Seven Segment Problems

Using Arduino Sensors
1

Hello, I have been experimenting with the Analog Pins on the Arduino Uno. I connected a potentiometer and a seven segment. What I want to do is when I rotate the potentiometer the numbers on the seven segment increases. I have attached the code that I have typed. I was just testing with the numbers ONE and TWO on the seven segment and nothing happened when I compiled and uploaded the code. I need help.

Thank You

The logic was a little off, but it looks like it should work. Put a longer delay between the states so you can see what is going on,

void loop()
{
	buttonValue = analogRead(pot);
	// the way you had it the code would always display "one"
	if ( (buttonValue >= 0) && (buttonValue <= 127) )
	{
                Serial.println("one");
		one();
		delay(300);
		off();
		delay(300);
	}
	
	 else if ( (buttonValue >= 128) && (buttonValue <= 255) )
	{
                Serial.println("two");
		two();
		delay(300);
		off();
		delay(300);
	}  

Serial.println(buttonValue);
}
