This was made from a sting of LED's purchased from Amazon. They were initially wired incorrectly, so I decided to start over. String consists of 20 white LED's (3v/20mA) and 10 blue LED's (3V/20mA). Each LED has a 220 ohm resistor dropping the current to about 8mV per. The entire circuit was then connected to a 5V USB power source that draws less than 250mA total. I added on a potentiometer to so the entire circuit could be dimmed. TikTok live 9-10-23
