Ricardo Moreno's video: Lesson 3 - LED

Lesson 3 – LED: learn how to change LED brightness with different values of resistors. Then I expand on the idea and add a potentiometer so that the LED can be varied in real time as a supplement to the tutorial. A beginner's guide to the Most Complete Starter Kit by Elegoo. Hello everyone, I'm Rick the Tech Enthusiast again, with the next lesson, Lesson 3 “LED”. This is the next lesson on my Arduino UNO Series covering the Most Complete Starter Kit by Elegoo. Now, I try to follow the tutorial closely, without overburdening the viewer with every detail, but I will point out any changes or corrections as I find them. As I mentioned before, I recently purchased this Arduino UNO R3 kit by Elegoo. No, Elegoo isn't sponsoring me. I just thought it would be fun to do a video of each Lesson as I was learning the Arduino environment. In this video, we’ll need a few things from your Elegoo Arduino kit. I’ll list the items below. In this lesson we’re going to learn how to change the brightness of an LED by using different values of resistors. Then I expand on the idea and add a potentiometer so that the LED can be varied in real time as a supplement to the tutorial. The tutorial goes into detail about breadboards, LEDs, and resistors so encourage everyone to review the material. In addition, I quickly go over LED voltage drop or Forward Voltage (Vf) and how to calculate the circuit’s current flow. This lesson uses the onboard 5 volt supply to drive the LED, so coding isn't necessary this time. Parts you’ll need: * Arduino UNO R3 board * 5mm red LED * 220 ohm resistor * 1K ohm resistor * 10K ohm resistor * 2 male-to-male wire jumpers * And the breadboard * (the 10K ohm potentiometer is also used to supplement the tutorial) The next Lesson will be Lesson 4 – RGB LED Links: (Note these are Amazon Associates links) (Full Disclosure: I get a little credit/$ if you purchase a linked item.) * LCD1602 Module with 3.3V Backlight 16x2 Character White on Blue Background by SunFounder: https://amzn.to/2KtsWk4 * Passive Buzzers, Cylewet 10Pcs 5V 2 Terminals, Arduino (Pack of 10) on Amazon’s web site: https://amzn.to/2z8SmhE * Elegoo EL-KIT-001 UNO R3 Project Complete Starter Kit with Tutorial for Arduino (63 Items) on Amazon’s web site: https://amzn.to/2KxZ8mA * Elegoo’s web site: https://www.elegoo.com/ https://www.elegoo.com/product/elegoo-uno-r3-project-complete-starter-kit/ Affiliate Links that Help my channel: * Try Prime Discounted Monthly Offering: https://amzn.to/2PnVgSA * Try Amazon Prime 30-Day Free Trial: https://amzn.to/2E5Hy4O * Prime Student 6-month Trial: https://amzn.to/2ElxwNE * Join Amazon Prime - Watch Thousands of Movies & TV Shows Anytime - Start Free Trial Now: https://amzn.to/2PsEZvE * Give the Gift of Amazon Prime https://amzn.to/2EkFaYG * Kindle Unlimited Membership Plans: https://amzn.to/2QJl548 * Try Audible and Get Two Free Audiobooks: https://amzn.to/2QD2B5v * Amazon.com - Read eBooks using the FREE Kindle Reading App on Most Devices: https://amzn.to/2Ptpdkl Music provided by Free Music Archive, by artist Jahzzar http://freemusicarchive.org/search/?sort=track_date_published&d=1&quicksearch=jahzzar This is the fourth video on a new Arduino tutorial series.
