I recently purchased a few LEDs for a project, 2 blues and four reds. I need a way to power them all for months at a time. Would a nice soul be kind enough to draw up a schematic for me, considering I know NOTHING about this stuff? Here are the schematics, taken right off the back of the packets.
4 Red LEDs:
Forward Current: 28mA max
Forward Voltage 2.6 V max
2 Blue LEDs
Forward (supply) Voltage: 3.7 typical, 4.5 Max
Forward (supply) current: 20mA typical, 30mA max
