I am building a model car for my daughter's birthday and lighting it with LEDs..
There are 4 white LEDs, 2 Yellow LEDs, and 2 red LEDs. These all have been tested with 3 v dc and light properly. as it stands, Ill need 24 v dc to power them..
Now comes the problem... I have 1 7.4 v purple (Ultraviolet) , and 2 pink. These also are 7.4 v. They do, however, light up with 9v.
My question is this...how can I, and what voltage do I need to power ALL at the same time. (I'm really a NOOB at electronics) so be simple please! Lol!
