This is a tool to help to compute resistor value depending on Vcc, 5mm LED color (and common accepted voltage and amperage). And this is a reminder of common things (colors meaning, led anode/cathode) in this area too.

* Choose the entry to change with up/down cursor keys or mouse
* Change the values with left/right cursor keys, everything will be automatically updated.
* If you let the mouse over a field a short help bubble will be shown
* W (Z on azerty) key or first button on a gamepad to disable Led lighting animation

It is a tool in a set of electronics helpers tools I started today, that you can found here: https://framagit.org/popolon/electronhelp
