Traffic Light Program on mBlock 3 w/Arduino Uno, LEDs & Functions

The video tutorial covers a project on creating a traffic light system using Arduino components and programming it with M Block, a software derived from Scratch 2.0. The instructor explains the setup, including the use of LEDs, jumper wires, and resistors, and demonstrates how to program the system according to the Hong Kong Traffic Light sequence. M Block's block-based programming is highlighted as a user-friendly tool for beginners. The tutorial also covers creating functions for better code organization and explores potential advanced features like adding sound, although not implemented in the demonstration.
