This is the first board I've ever designed and I've seen a lot of boards have complicated copper areas and mine has none. I was wondering if someone could help me out with my design if i need to change anything. Also anybody educated in LEDS could you help me. From my design I have 11 SMD green LEDs in parallel I think. Most green LEDs have a forward voltage of 2.4V. Im powering my circuit with a 1220 coin cell which is 3V. Do i need a resistor after my switch to not kill my LEDs.
Thank you.![enter image description here][1]
