Methods for Powering 8 LEDs? Answered
Hey Guys - My daughter has a small Little Tikes car which I'm adding 8 LEDs (3 per headlight & 1 per taillight) to. Each LED is a 2v 20ma. I've already started, but hit a snag. For testing the LEDs, I used a 9v battery with a 330ohm resistor on positive. This lit individual LEDs as well as 3 LEDs in parallel. My plan was to wire them all in sequentially then figure out what was needed resistor wise when done - bad decision. I have almost everything installed except power and now stuck as to what do do. Having 8 LEDs which are 2V / 20ma, exceeds the voltage a 9V battery can produce. Afraid to try connecting the 8 directly to 9V as don't want to risk burning them out. Just wanted to post to see what my best option would be - especially one where I wouldn't have to rewire everything again in parallel if at all possible. Thanks!
