"Traffic light of a street with a pedestrian crossing."

#IEEEDay

Objective:
Build an automated traffic light for vehicles that allows pedestrian crossing through the activation of a button, using an Arduino Uno and basic electronic components.

Required Materials:

• 2 red LEDs

• 1 yellow LED

• 2 green LEDs

• 5 resistors of 220Ω

• 1 resistor of 1KΩ

• 1 Arduino Uno

• 1 push button

• 1 breadboard

• 1 9V battery

• 1 9V battery clip with Jack

• Connection wires

Activity Development:

a) Introduction:
A brief explanation will be given about the components to be used and how they should be connected.

b) Circuit Assembly:

1. A sheet with information about the components and how to connect them will be provided.

2. Students should follow the image to make the connection.

3. Once the assembly is complete, the circuit will be reviewed and powered with the 9V battery.

c) Arduino Programming:

1. The program will be preloaded onto the Arduino Uno.

d) Testing and Adjustments:

1. Verify the operation of the circuit and the code.

2. Conduct tests with different traffic light timing changes.

Evaluation:

• It will be assessed whether the circuit is correctly assembled.

• The proper functioning of the traffic light in its normal cycle and with button activation will be verified.

• Participants' understanding of the logic behind the Arduino code will be analyzed.

Conclusion:
A reflection will be made on the learning obtained from the activity.

Estimated Time:
Approximately 60 minutes.
