Hey everyone,
So I am looking to create a battery powered LED sign using approximately 30-50 LED's arranged in a pattern. The ratings on the LED's are 2V at 20mA. The battery power source I would like to use is either a 9V or one of those big 6V.
My question is what configuration would be best for wiring these together (series, parallel or both) and at what positions do the resistors need to be integrated into the circuit? It would be helpful to learn how to calculate the correct values for the resistors needed for the configuration as well.
I have also been looking for a way to find out how long the battery would last for such setup but have not been able to find out.
Any help would be great,
Thanks,
M
