Arduino Led Very Dim at Harry Marconi blog

Arduino Led Very Dim. I know that the port/led is. The green led works perfectly. I am kind of new to arduino so i watched a tutorial, and everything works fine except the light is very dim. Either you have a low. Dim to the point that all you see is a small dot of light in the led. The first 4 light up in sequence fine, and if i light up just the last one it lights up fine, but if all 5 are lit at once the very last led is very dim. When testing with a multimeter, the pin only gave. All of my green leds are very dim. The green led turns off if the sensor detects a vibration. I am trying to light up 5 leds as part of the project. I usually use a 220 ohm resistor and it is always very dim. All of my other leds are bright. Is this normal and can i make it brighter? So a red led would need about 50% more. When the pin goes high the led goes on but is very dim.

When i tested my led on a digital output pin that was assigned the value of output, it only lights up the led very dimly even with no resistors. I know that the port/led is.
