Скачать или смотреть Resistors for LED Wiring Followup and Free Download

I created an Excel spreadsheet and PDF reference file for looking up what resistor to use for different combinations of power supplies and LEDs. You can download the PDF file I show in the video here:

The download is free but I would appreciate your subscribtion to this channel.

Here are common resistors used with 1.5v LEDs with a 12 volt power supply.

Buy 560 ohm 1/4 watt resistors: http://amzn.to/2sRll1G
Buy 560 ohm 1/2 watt resistors: https://amzn.to/2D7VWJd
both will work, the 1/2 watt resistors will stay cooler, however.
