Dot matrix display
@David_Robert is the rest of your message lost 
@Yves_BAZIN just wanted to draw attention. I am having a hard time finding getting my dot first dot matrix display to work. I was wondering if anyone has a working one that I can learn from
@David_Robert what’s your setup ( controller, LED type, number of pixels, power supply)?
Post your code on http://gist.github.com and share the link here.
I used AT89S52 controller, 7by8 matrix display power supply is 5v DC
I’ve tried my best to upload the code through the website but it’s not working. Problem creating an account on the site. I really need help with this stuff.
An account is not required to put code on http://gist.github.com/
You should be able to paste your code in the box and click either the “create secret gist” or the “create public gist” button.
Also, what type of pixels are in your matrix display, and how many Amps can your power supply provide?
I really don’t understand the concept of pixels here
Different types of pixels use different chipsets. You have to know what type of pixels you have so you can tell the controller to send the correct data that the pixel will understand and be able to display. If you send the wrong type of data it won’t hurt the pixels, but they will not light up or maybe will light up completely wrong.
Common pixel types used by many here are WS2812 and APA102.
I used single led bulbs from electronic store
This is the link for the code https://gist.github.com/anonymous/ae5514f4632568a9d1f15d43d99ecc3f
Regular single color LED with only a + and - wire? Or something else?
Can you post a photo or link to your bulbs?
Single leds, red color
While it is possible to use the FastLED library to control simple single color LEDs, this group is mostly dedicated to using addressable RGB LEDs. What you are doing sounds very different from most projects post here. Also it doesn’t look like you are using the FastLED library in your code.
