Data Sheet
INTRODUCTION
Interactive Trac Light is a combination of standard trac light for
vehicles and trac light for pedestrian.
This project applies knowledge outcome from:
Lesson 1: LED Blinking
Lesson 6: Push Button as Digital Input
INGREDIENTS
a. Maker UNO - 1x
b. Breadbord - 1x
c. Red LED - 2x
d. Green LED - 2x
e. Yellow LED - 1x
f. Push button - 1x
g. Resistor 220Ω - 5x
h. Resistor 10kΩ - 1x
i. Jumper wires
INSTRUCTION
Using all the parts above to create a simple trac light system for vehicles and
pedestrian. At start/normal condition, green LED (vehicle) and red LED
(pedestrian) will light up. When push button is pressed, green LED (vehicle) will
turn o and yellow LED (vehicle) will turn on for 2 seconds. After that, yellow LED
(vehicle) will turn o and red LED (vehicle) will light up. After 1 second, when it is
time for pedestrians to cross the road, green LED (pedestrian) will turn on for 5
seconds. Then, green LED (pedestrian) will turn o and red LED (pedestrian) will
turn on. After 1 second, it will be back to normal condition.
