What courses (knowledge) do you need to learn and what components do you need to control 100 LEDs by computer?

Scheme 1: industrial programmable controller (PLC) is adopted, which is widely used in industrial production. It is a standard part, with low price, stable performance and easy programming (factory electrician, with a lot of junior high school education, you can learn it within one week, provided you have basic knowledge of electrician).

Applicable environment: industrial production

For example, there are 100 string lights in the park light show, which should flash according to the preset program.

At this time, you can consider buying a PLC with 100 relay output node. If the output switching frequency is high, you can consider buying a PLC with 100 solid-state relay output node.

Scheme 2: If 100 LEDs are only arranged in a square array to display characters, you can buy character display modules and plug-ins from professional manufacturers and connect them with ordinary computers. After installing the driver, you can input the corresponding characters and patterns without programming.
