Need help designing an LED circuit for a fancy hoola hoop?
My girlfriend has asked me to help her make a blinged up hoola hoop for a class she is taking. I have some clear tubing to make the hoop, a small holder for 2AA batteries that fit inside the tube and have purchased 20 LED lights to go inside. My question is, what is the best way to wire these LEDs to make use of the 3v from the batteries. The stats on the LEDs are as follows: (Max forward current 20mA continious, 5VDC Max reverse Voltage. 4VDC Forward voltage drop)
Thanks for any help or ideas!
