When building projects with the Arduino, I often need to use a specific resistor value or calculate what resistor value I will need to power an LED or some other component. This usually requires me googling 'resistor color calculator' or 'ohms law calc' to get to a website that can make these calculations quick and easy.
Because I usually end up going to a different site each time I search for one of these tools, I decided it might be fun to build some calculators in Ruby and add them to my website for easy access. You might already have a site or two bookmarked but if not, feel free to use my site.
If you are a Ruby programmer and have any suggestions or just want to play with the calculator, feel free to check it out here:
That is all.
