Materials Needed:
- Three LEDs (Red, Yellow, Green)
- Resistors (appropriate values for the LEDs, typically around 220 ohms)
- Breadboard or PCB (Printed Circuit Board)
- Jumper wires
- Arduino or microcontroller (optional)
- 9V battery or power supply (optional)
- Small project enclosure or case (optional)
- Hot glue gun
- Acrylic or colored paper
- Craft sticks or cardboard
- Paints (red, yellow, green)
- Paintbrushes
Tools Needed:
- Soldering iron and solder
- Wire stripper
- Scissors
- Craft knife
- Ruler
- Pencil
Steps:
1. Prepare LEDs and Resistors
a. Identify the positive and negative leads of each LED. b. Solder a resistor to the positive lead of each LED.
2. Assemble the Circuit
a. Connect the LEDs and resistors on the breadboard or PCB. b. Connect the negative leads of the LEDs to the common ground.
3. Wiring
a. Use jumper wires to connect the positive leads of the LEDs to the appropriate output pins on the breadboard or PCB. b. If using an Arduino or microcontroller, connect the control pins accordingly.
4. Optional: Arduino Programming
a. If using an Arduino, write a simple program to control the LEDs in a traffic light sequence (Red, Yellow, Green).
5. Create the Traffic Light Housing
a. Cut the craft sticks or cardboard to create the frame for the traffic light. b. Paint the craft sticks or cardboard in the colors of a typical traffic light: red, yellow, and green.
6. Attach LEDs to the Housing
a. Glue the LEDs into position on the craft sticks or cardboard, corresponding to the colors of a traffic light.
7. Optional: Enclosure
a. Place the traffic light model inside a small project enclosure or case for a polished look. b. Secure the components inside using hot glue.
8. Decorate
a. Use colored paper or acrylic to add additional details to the traffic light. b. Customize the housing to resemble a real traffic light.
9. Final Touches
a. Ensure that all components are securely attached. b. Test the traffic light model to see the sequence in action.
