Construct a Arduino Traffic Light Module

Introduction

The PCBWay and Silícios Lab are interested to incentive the STEAM education and all hobbyists around the world to create several projects with simple printed circuit boards for Arduino.

In this article, our aim is to present the project of the traffic light circuit board and offer 10 free units for you in the PCBWay.

Now, we'll present the project of the traffic light printed circuit board.

You can access the traffic light module files through my repository projects: http://bit.ly/2WhO79V

Development Project

This project is very simples. Basically, is need to connect three LED's with current limiting resistor and the header male, to be connected in the protoboard. The schematic circuit is shown in Figure 2.

After drawing the circuit schematic, itis needs to draw and generate the layout of the printed circuit board. The printed circuit board schematic is presented in Figure 3.

Hereafter, we present the 3D circuit of the board in Figure 4.

Therefore, through this system is possible to develop several activities and projects for makers and hobbyists of the Arduino boards. Now, you can obtain and earn your own board traffic light to develop your projects and ideas.

Conclusion

Through this simple project, it was possible to develop the traffic light board and generate its Gerber files for productions. All files are available in the PCBWay repository through this link: http://bit.ly/2WhO79V
