For those who have trouble calculating LED series resistors or voltage dividers, a calculator page is available at Digikey. In fact, many different calculators are available, such as

• LED series resistor
• Voltage dividers (do note: a voltage divider isn't designed to power a load!)
• 550 timer calculator
• Passive high and low pass filters
• Temperature conversion
• Length conversions
• Force conversions
• Number base conversions?

The list of calculators available is too long to post here. It's a worthwhile page to check out.
