Arduino UNO R3 Clone and Baud Rates: Tackling the 180 LED Challenge

Other Hardware 3rd Party Boards

I am using an Arduino UNO R3 clone, and I'm wondering if increasing the Baud Rates speed could potentially harm the board. Additionally, I have 180 LEDs, and I'm curious if I can run them smoothly with this board. Can I achieve this by increasing the Baud Rates?

Welcome to the forum

Increasing the baud rate of the Serial interface will not harm the Arduino. Whether it works properly at the selected baud rate is another thing

What sort of LEDs are you using ? Are they individually addressable, RGB or a simple LED strip ?

The baud rate relates to the Serial interface. It would be unusual if that had anything to do with controlling LEDs connected to the board

Thank you for your answer. I am using separately addressable led

Then you need to take account of the memory needed. Each LED in the strip needs 3 bytes so 180 LEDs needs 540 bytes. This is about a quarter of the memory available on a Uno so be careful with how much memory you use for other purposes

However, as previously mentioned, the serial baud rate has nothing to do with controlling the addressable LEDs

Why are you asking about increasing the baud rate ?

Because in the prizmatik application, when I select the USB port at the first stage in the installation, it asks me to select the baud rate speed.

It also increases the number of 180 leds to control the number of leds, so I hope it is understandable when you see the led ambience by increasing the results

Is this a PC application? What does this have to do with Arduino?

I wanted to tell you if there is a problem with this high baud rate so that I can run my Ardiuno device.

Run what? Is there a version of prizmatik that runs on an Arduino?

Or are you just asking if you can use that many addressable LEDs with an Arduino using a library, because as you've been told, that has nothing to do with baud rate.

Which addressable LEDs?

One WS2812 LED requires 30 microceconds to update; 180 in a row is 180 x 30 = 5400 microseconds (5.4 milliseconds).

During that time the FastLED and Neopixel libraries (if you use those) will disable interrupts and you run the risk that you loose serial data when the app sends more than 2 (or was it 3) bytes at that time.
