This was one of my first projects in any CEIS setting. This made me fall in love with the industry. I used pre-written code to familiarize myself with the concept and this is where I started my coding journey. In this project, I created an intelligent crosswalk using LED and C# code.

2. Introduction
 This digital devices class has given me so many career skills I don’t know
where to start. Not just the specific career knowledge but life knowledge
that will follow me forever. Problem solving is key to anything in life and in
the workplace and any CEIS student will tell you the problem solving is
key. For this course I built a smart traffic light system an I will now take you
through that process.

3. The First Step
 A part inventory was the first step and configuring my board to the
Arduino IDE.

4. A Challenge
 During this time I had only used a Arduino MEGABOARD and the ESP was
a whole new world. The ESP was a very easy learning curve and I now have
a new trick in my sleve.

 ESP 32 Board
 Colored LEDs: Red, Yellow,
Green, and Blue
 220 Ohm Resistors (optional)
 Wires
 Breadboard(s)
 LCD Unit with I2C Adapter
 Active Buzzer
 Mini Router
 Push Button(s)
 PIR Motion Sensor

9. Step 2
 Now was the time I had to test my board and LED’s. A challenge I faced
was troubleshooting the IDE with the new board.

12. Step 3
 Now it was time to add more wires and LED’s to the board. I faced a lot of
troubles connecting to the proper GPIO.

 ESP 32 Board
 Colored LEDs: Red, Yellow and
Green (two sets)
 220 Ohm Resistors (optional)
 Wires
 Breadboard

15. Step 4
 Next was The start to the stop light system. I had trouble getting the code
in the IDE properly.

19. Step 5
 Next it was time to add a LED panel and buzzer and this was a challenge.
It was tough to configure the LED panel to be able to show the text.

23. Step 6
 Now it was time to finalize the project with the motion sensor. This a lot of
extra parts and it got a little confusing.

27. In Conclusion
 This project taught me more about digital devices than ever. I also gained
a lot on trouble shooting IDE’s. Thank you for watching.
