LED & electronics newbie project
Im brand spanking new to electronics so i have a few questions here on LEDs.
If you connect say 20 LEDs in series, can you still power them with regular batteries (1.5V)?
I would like to use the mains to power the LEDs. I have various adapters lying around ranging grom 5V to 12V. What changes, if any, will I have to make to the configuration and will I need extra components?
I want to make lighting for a very small permanently dark room where I can use a switch to turn on the LED lights.
