In programming, many typical tasks have standard solutions. A good example of such tasks is the time counting in both sides - a counter and a timer. Often, as part of the algorithm either need to count the time, or wait for a certain period of time to elapse. In our material, we consider both cases.
Counter on WeDo 2.0 Toolbox
To program a counter algorithm from 0 to 10 in the WeDo 2.0 toolbox, you will need:
1) Set a white background to the block «Display Background» (number «0»).
2) Set the « Display Block, 123» to the initial value from which the count will be taken (usually the value is «0»). This is the operation that programmers call initialization.
3) Set the number of repetitions for the loop (Repeat Block), for example, - 10 times.
4) Each time the cycle is repeated, add «+1» to the value recorded in the screen memory. In turn, this command in programming is called an increment.
5) Set a "Wait for" block with a value of 1 second.
Timer on WeDo 2.0 Toolbox
To program a timer algorithm from 0 to 10 in the WeDo 2.0 toolbox, you will need:
1) Set a white background to the block «Display Background» (number «0»).
2) Set the « Display Block, 123» to the initial value from which the count will be taken (in our case the value is «10»). This is the operation that programmers call initialization.
3) Set the number of repetitions for the loop (Repeat Block), for example, - 10 times.
4) Each time the cycle is repeated, subtract «-1» from the value recorded in the screen memory. In turn, this command in programming is called a decrement.
5) Set a "Wait for" block with a value of 1 second
