Project I - 20. Running Text using LCD Matrix P10 Module (Arduino Uno Based)

Running Text using LCD Matrix P10 Module

Arduino send "text" data to the Matrix P10 Module and the text will be shown from right - to - left.

Hardware Requirement

• LED Matrix P10 Module
• Arduino UNO
• Power supply +5 Volt
