Everyday Coding
Although we can’t see them, codes are all around us, helping us every day. Computers use code to make modern technology run smoothly. Here are some examples of coding in everyday life.
Traffic lights
Coding is used to control the flow of traffic in many towns and cities. A computer sends coded instructions to the traffic lights to tell them when to change color. Drivers and people on foot then know when to stop and when to go.
Computer games
Computer games can take players to imaginary worlds. Every game has code working behind the scenes that becomes instructions to make your character jump high or your car go faster.
Vending machines
After you have inserted money and made your selection from a vending machine, the code will figure out how much change you need, and then drop your item down to a tray for you to pick up.
Microwaves
Simple coded instructions control the timer on your microwave and the temperature your food is cooked at. The code starts working when you press the buttons on the microwave.
Barcode scanner
Every item in a store has a unique code of lines to identify it. These lines, or barcodes, are read by a computer that finds the item and its price in a database so you can buy it.
Vehicles
Cars use computer code to monitor their engines and make sure they run well. Code also controls things like the blinkers on the dashboard and windshield wipers.
Calculator
Calculators use code to figure out the answers to mathematical questions. They display the results immediately on the screen.
Smartboard
These giant screens use computer coded instructions to let students choose and control what information is shown. All they have to do is touch the screen.
