------------------------------------------------------------------------------
Welcome to our channel! In this video, we present our 10-channel traffic light controller with additional button options. This versatile device supports AC voltage for both input and output, ranging from 0 to 220 volts. The input frequency can be 50Hz or 60Hz, automatically detected by the Arduino-based Nano chip.
The pre-loaded sketch on the board simplifies its initial use. Today, we'll demonstrate how to modify the existing sketch using a computer connected via a USB Type-C cable. We'll guide you through the process step by step.
The board features identification characters (L1 to L10) for each output, and the corresponding GPIO numbers for Arduino Nano. For example, L4 corresponds to GPIO 06. We've included buttons and communication features like transmitter and receiver SDA, allowing easy interaction and communication with other boards.
Safety is crucial when working with AC input. While the board can handle low-power DC voltage (5V, 2A), exercise caution with AC input to avoid potential dangers.
The video explores the Arduino coding, emphasizing the importance of basic Arduino knowledge. Despite being labeled as a traffic light controller, the device can be adapted for various applications involving AC devices.
The demonstration covers button functionalities, indicating button presses and corresponding outputs. The video walks through the process of modifying the sketch, addressing potential errors, and uploading the code to the board.
The code adjustments include changing delay times and selecting the appropriate Arduino processor and bootloader. The video concludes with a faster demonstration of the modified code.
For viewers interested in replicating or customizing the project, the video provides insights into Arduino programming and troubleshooting. Feel free to ask questions, and thank you for watching! Have a great day!
