Micro:bit Stopwatch

I always wanted to know how a timer worked and I think it is good to know how a timer works

A timer is handy to have wen you want to know how long something takes to do or if you want to time something and that is why I am going to make a timer 

1x BBC micro:bit

1x Computer to make and upload program/code

1x USB cable

this program is made in Microsoft https://makecode.microbit.org/ and I will guid you step by step

wen you are in Microsoft MakeCode klik on new project and then follow these steps

take (on button A pressed)  from input and place it .

make a variable named start in variables then take (set start to) and place it in (on button A pressed).

then go to input more and take (running time ms) and place it in (set start to).

next take a (on butten A pressed) and change the letter to B and place it separately from the first one.

make a new variable named elapsed and then take (set elapsed to) and place it in (on button B pressed).

go to math and take (0-0) and place it in (set elapsed to).

then go input more and take (running time ms) and place it in the left side of (0-0).

go to variables and take (start) and place it in the right side of (0-0).

then go to basic and take (show number 0) and place it in (on butten B pressed) onder (set elapsed to)

go to math and take (0/0) and place it in (show number 0)

then place the varieble named (elapsed) in the left side of (0/0)

and in the right side of (0/0) you typ 1000

that is the code

Use the emulator to test the program. if it doesn't work you can change the code

Simply download the program from the bebsite and then upload it into the micro:bit

have fune with your new stopwatch and try to time your 100m sprint
