Technical Notes

Helpful Technical Notes and Information

We produce and collect a lot of information and notes in our travels and visitors to are continually looking for that at one time or another. We will link to all the information we gather from these pages as we identify them. The page contains a collection of technical notes and documents to assist in providing a reference library of different documents to aid in the design and creation of your projects.

Do you have a document or information that other guests might benefit from? If so, feel free to contact us, and we can include your information on our list.

Document Title Details
LED Series Dropping Resistor Calculator All LEDs require current limiting, without a current limiting mechanism, LEDs will burn out. Adding a simple resistor is one of the easiest ways to limit the current. Our two online calculators allow for the automatic calculation of the necessary current limiting resistor and power rating for either running a single LED from a power source or running multiple LEDs in series from a power source.
Resistor Color-Code Value Calculator The color code is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, and others. Our online tool allows for the entering of the color code on your resistor and will display the actual resistance value.
