Title: Controlling 100 LEDs separately using Arduino!
Post by: majith_ismail on Jan 25, 2018, 01:36 pm
I'm into a visible light communication project where I have a 10x10 LED matrix! These LEDs have to be separately controlled to send bits 1s and 0s. Is multiplexing a solution using shift registers? I have to transmit data at a specific rate like say 30bits/sec using one LED! Ive attached the datasheet of the LED im going to use. The colour is Blue-Green.

Do you have a design sheet for the project which states the requirements and goals of the project?
Do you have a design sheet for the 10x10 matrix?
Do you have a schematic for the 10x10 matrix?
Any links to the project?

Have you all ready built the 10x10 matrix?

Which Arduino Board are you using?
Which version of the Arduino IDE are you using?
What operating system are you using?
Linux, MacOSX, MS Windows, other

No, I haven't started the project yet! I haven't built the LED matrix yet either. I need to know whether it is possible to gain a signal rate I've specified.
I need to separately control the 100 LEDs using shift registers!


I'm using an Arduino Uno
Arduino IDE 1.8.5
MS Windows

the answer will depend on how the leds are wired.
100 LED wired point-to-point would be a challenge.

I have to think about this and draw it out.

Perhaps this thread will give you some ideas.
