Project 1.4.1: RED MEANS STOP

Description This teaches you how to turn ON and also turn OFF the red light only on the traffic light module.
Use case Programming the red light on the traffic to turn ON which will signal drivers and riders to stop.

Components (Things You will need)

Traffic light module Arduino Uno Arduino USB Cable Breadboard Jumper Wires

Building the circuit

Things Needed:

  • Arduino Uno = 1
  • Arduino USB cable = 1
  • Traffic light module = 1
  • Red jumper wires = 1
  • White jumper wire= 1

Mounting the component on the breadboard

Step 1: Take the Traffic light and the breadboard, insert the Traffic light into the horizontal connectors on the breadboard.

step 2: Connect the R pin of the traffic light module to pin 5 on the Arduino Uno using a jumper wire.

step 3: Connect the GND pin of the traffic light module to GND on the Arduino Uno.

step 4: After wiring, connect the Arduino Uno to the computer using the USB cable.

PROGRAMMING

Step 1: Open your Arduino IDE. See how to set up here: Getting Started.

Step 2: Type const int red = 5; before the void setup function.

Pinmode decalration.

Step 3: Type the following codes in the void setup function as shown below;

pinMode (red, OUTPUT);

Trafic pinMode.

Step 4: Type the following codes in the void loop function as shown below;

digitalWrite (red, HIGH);

Truning On the Trafic ligth .

The digitalWrite () function controls the state of the pin. The pin can either be HIGH or LOW. The HIGH state turns on the LED. As a result, the code below turns on the LED.

NB: To turn off the traffic light Step 5: Change the digitalWrite (red, HIGH); into digitalWrite (red, LOW);.

Uploading the code

Step 1: Save your code. See the Getting Started section

Step 2: Select the arduino board and port See the Getting Started section:Selecting Arduino Board Type and Uploading your code.

Step 3: Upload your code. See the Getting Started section:Selecting Arduino Board Type and Uploading your code

CONCLUSION

summary, the project centered on the illumination of a red light in a simulated traffic light system provides a fundamental understanding of basic electronics and visual signaling. By lighting the red LED, participants grasp the concept of circuit connections, output control, and the role of color-coded signals. This undertaking serves as a cornerstone in electronics exploration, illustrating the significance of clear visual cues and sparking interest in practical applications, such as traffic management and safety systems.
