In this weeks video we’ll take a look at how to use an LED. There are tons of LED related projects out there but what if you want to integrate LEDs in your own project? When your finished with this video you’ll be able to pick the appropriate type of LED for your project and know how to current limit it using a resistor.
How to Use an LED
Why is the resistor(s) after the LEDs and not before ?
Sorry to take so long to replay to your question. In these cases it really doesn’t matter whether the resistor goes before or after the LEDs. The main reason they are there is to limit the amount of current being drawn from the source. This can be done anywhere along the branch. Thanks for the comment!
Thanks! I enjoy your videos.
