How do addressable LEDs work?
By contrast, individually addressable LEDS have a tiny microcontroller on each of the LEDs to allows each one to light up with a unique color and brightness. The strips have a positive voltage wire, a ground, and a data wire. Each time the data reaches an led it is read and passed down the strip to the next led. first chip reads the incoming address as LED0, and then performs the instructions for LED0, it also passes the data on to the next chip after increasing the counter value by 1. In other words, the first LED says “Okay, I’m LED0, the next guy who gets this message is LED1”, this message continues down the strip until there are no more LEDS left. The important thing for you to know here is that each LED in the strip needs to be given specific instructions with their specific address.
How many different colors of light are in a 3 channel strip?
A 3 channel strip has 3 different ground circuits and one common voltage, each different ground channel controls a different color of light (Red, Green, or Blue). By changing the resistance on those channels you can change the brightness of each channel, which allows you to produce a wide range of resulting colors.
How to calculate LED timer?
This calculation is pretty simple, we just take the total number of minutes for the timer, and divide it by the total number of LEDs in our strip which will give us the fraction of a minute that each LED represents. Since the simple timer library for Arduino wants an input of milliseconds we’ll also need to multiply by 60,000 to convert from minutes to milliseconds. We’ll use this number of seconds to tell our program how often it should subtract an LED from the ledsRemaining variable. In the simplest situation if we had 60 leds total in our strip and we set our timer for 1 minute each LED would last for only 1 second.
How many times does a loop turn on LEDs?
You can see that each time the loop runs it will turn on a different LED based on the value of that variable “.”, if the ledsRemaining variable is equal to 25 it will run 25 times and turn on LEDs 0-24. If my ledsRemaining variable is equal to 8 it will run 8 times and turn on LEDs 0-7.
