Visit this project on github to view the source code.

This tool will assist in 4 tasks.

1) LED Drop Calculator
2) MCD to Lumens Converter
3) Ohm Calculator
4) Resistor Selector

This app has a 100% functional Ohm Calculator along with a Resistor Selector. There is future functionality for LED Drop calculators, MCD to Lumens converters, an LED Series Resistor selector and a few other tools. If you would like to suggest an Electrical Engineering tool please do. If I can add it I will. I began this project because of my interest in the Arduino platform. If there are Arduino related tools I can implement please let me know as well. As soon as I find some more time I will release another update.


Thanks for using my app so far. The most recent update implemented the following changes.
1. Instead of selecting which tool to use from the menu, it's now a slide out menu. This is more in line with Google's stock apps (like Google+ and Gmail).
2. I removed the background and selected colors that are accessible for those who are colorblind. This also keeps the app more in line with stock Google apps.
3. Resistor Selector has 100% functionality. Please take a screen shot and press contact developer if you encounter any incorrect results.
4. NumberPad done functionality on the Ohm Calculator.

The Next updates include
1) LED Drop Calculator
2) MCD to Lumens Converter
3) Astable Circuit Calculator
4) LED Series Resistor Calculator
5) Information about the Developer

I would be grateful for any feedback as you use my application.

This app will be open sourced eventually and I will link to the GitHub. There will also be a blog about how each portion of the app works. I've learned a lot and would like that information to be available to the public.

This app will always remain ad free, tracking free and actual real money free.

Excellent! Finally, a straightforward, no-nonsense OHM's law calculator! 10/10 A++!

James Olley

Updated menu! Nice update. Crisp and easy to navigate

Rob Edmondson

Works well Look forward to resistor band calculator

Jeff Miller

Love it! Really clean and easy to use. Does exactly what it says.

Barabas Rozsa

Ugh Good idea, auto reset or continued calculate would be nice. Not doing lower currents. Under 1A...

ambion kanai

One tweak will make it great It would be nice if the actual units of measurement could be displayed- for those of use who aren't that familiar with electricity. Sorry, but my GCSE curriculum didn't really cover this.

Khat Nip

Great! Simple and accurate.

Ahad Karim

Does what it is required to do.

Senior Vapors

Time saver Works great, even @ builds lower than I will use ♎??
