Day 1 of Race Countdown Game

This is my first hardware project

LEDs

• LED starts as a countdown, so each light represents a number counting down from 3
• Example: red represents 3, yellow, represents 2…

Connected the LEDs to the breadboard and used 220 ohm resistors. Then I connected the breadboard jumper wires to the I/O pins.

The Ultrasonic

My idea is that a person will start the game and there will be a countdown. This game will be a reaction game. The person will put their car behind the ultrasonic sensor.
If the person launches the car after the green, they win, but if they do it to early, they lose.

Display Module

• Shows 3, 2, 1
• Shows you lost or won
• the shows your reaction time

Need to create more code to use display and sensor
