LED Resistor Dial Selector [Tools]
posted October 31 2014 15:28.46 by Giorgos Lazaridis




I made this project back in 2012. Its a very simple tool useful for the amateur electronic enthusiasts. You can DIY by simply printing a PDF file, and following the instructions here. Then you can use this dial selector to select the proper resistor value to protect your LEDs in circuits. Here is how it works:
