Learning Traffic Light in LED

IMG_8136.jpeg

This project is about letting children know about different lights and know them quickly. Children that are small can also have this chance to know and memorize different colors. By using three light colors which are green, yellow, and red, children can get used to the lights of traffic lights. Also, by letting the LED light bulb shine randomly, students can refer to the question and answer which color is it. This can let children be familiar with colors and some basic colors that will be used in life.

Supplies

- Jumper Wire (3)

- Arduino Leonardo (1)

- LED Light Bulbs (Green, Yellow, Red) - Resistance (3)

- Bread Board (1)

- USB Cable for Arduino (1)

Complete the Circus

IMG_8137.jpeg

1. Connect a Jumper Wire to GND and negative

2. Connect d12 to the positive of a green LED light bulb by a jumper wire

3. Connect d11 to the positive of a yellow LED light bulb by a jumper wire

4. Connect d10 to the positive of a red LED light bulb by a jumper wire

5. Use resistance to connect the negative of the light bulb to the negative of the breadboard

6. Connect the computer and the board with a USB cable

Make the Covering Box

IMG_8138.jpeg

1. Prepare any paperboard or cardboard

2. Cut them into a size that can totally cover up the whole breadboard

3. Cut out three holes in the front

4. The three holes should be in referring to the three LED light bulbs

5. Cover up the three holes with glassine
