hello everyone,
sorry for my English but I'll try to do my best ...

I have a conditional problem,
my project is a proximity sensor that sends values (​​float, from 0 to 1) to a LED who lights up depending on the intensity of the sensor
The LED should work only if my values ​​are greater than 0.2.

I have wrote:

[sensor values (0 to 1) ]
|
|
[>0.2]
|
|
[analog output (led)]

my problem is that the result is a boolean and i need a float result after >0.2
What can i do please?

[moses 0.2]

ok thank you, i have a float result now..
but I have an other problem now because I want my LED
is switched off between 0 and 0.2 and when she light up,
i want that the light have the minimum of intensity...

i try a lot of thing but I can not find how to do this.

thank you for answer

[moses 0.2]
| /
[0( [- 0.2] <-- subtract whatever the minimum intensity is
| /
| /
| /
| /
| /
(analog output)

that's what I tried to do, but the LED continues to light up below 0.15.
I also tried it with [sel 0] for the left value under moses 0.15 but the right value doesn't subtracted anymore.

Hello everybody:
I posted recently an abstraction for mapping an input range to an output range. Check on this thread, it may help:

If you use the input range as (0.2, 1] and the output range as [0, 1] it should do what you want.

All the best for all of you,

Sumidero

silas202, that [0( in my comment is not a number box, it is a message box. Please read the stickies at the top of the "technical issues" section to get a better understanding of the ASCII art patches.

thank you maelstrom it works now!
but the object [-0.025] to init the result doesn't work!

sumidero thanks too il will try to use your patch

[moses .025] isn't going to send anything out of it's right outlet if the incoming value is below .025, so that right number box won't be updated. Connect them to the same numberbox, and you should see that it does work.

[moses .025]
| /
[0( [- .025]

[numberbox\

thank you very much!
all is good! (i hope...)
i will show you my project in two week
