You need to be a bit more descriptive. What is it for and what will trigger its generation.

If it is triggered by a button press, you could rely on how long the button is pressed for to generate the number since even the PICAXE can do it faster than a human can time it to get the time they want. This is a brief idea of how it could work although I can't guarantee that it will as I'm not sure about conditions for exiting a loop.

A better response will come from someone else.

You can use the random command to put a byte (0-255) into a variable (e.g. A). You will then need to scale this and use loops.

As a rough example, take the values 0-30 to mean 30, which makes 3 minute.
Take any other value 30-255 to give you 3 to 25.5 minutes.

So a value of 10 means 1 minute, value of 1 means 6 seconds.

So use a flowchart which is the equivalent of

random A
if A < 30 then A = 30
B = 0

do while B < A
wait 6
inc B
loop

What I am after is my program to go into a random wait of 3 to 30 minutes after this time runs then goes into the wait again.

@driedeker

Follow Technical's code and convert it into a flowchart.

Hi guys. I'm a massive, massive, massive, massive noob to all this, but I need a little help making a random timer for school.

Basically I'm making a reaction game, and I want the LED to light up at any random time between 3 and 6 seconds

I'd be really grateful if you could give this to me in a flowchart format

Thanks!!

@Briski - which part are you stuck on? Don't forget you can also ask your teacher.

I'm not at school for another week

And I just have no idea which commands to use

 

[nick12ab]

Look at the Random and Compare (If) commands in Logicator help. Basically, what you can do is use Random to generate a number and use Compares to check that the generated variable is within the limits you want, and if not, generate the number again until it is.

Sorry to be a bit of a pain, but I don't really get how to use the compare function

Within Logicator, clicking on the Help menu option will lead you to detailed information on each command. Particularly useful are -

Help -> Contents

Help -> Manuals -> Logicator Manual

So how would the compare command work with the random command?

 

[nick12ab]

You use the random command first then two compare commands as shown below.

You just use the three blue shapes as shown and they're inserted into your program.

Aha thank you so much for your help. That was what I was looking for
