Can someone advise how to get power low enough to power this bag of Amazon LEDs without blowing them out, as I have been doing. These are them: MCIGICM 5mm LED Light Diodes, LED Circuit Assorted Kit for Science Project Experiment (Multi-Colored - 5 Color)
I went to Digikey to get 220 ohm and 330 ohm resistor arrays. 8 resistors in a 16 pin IC chip. I use them instead of resistors for LEDs. You need a resistor on each LED.
