QUESTION

Why does this Arduino code not color-fade correctly, while the Python equivalent does?

Asked 2021-Nov-22 at 21:47

I'm trying to write a program for my Arduino Uno that slowly fades through different colors with an RGB LED. The problem is, that instead of slowly fading, it quickly blinks several different colors, and then fades through just a couple colors. It then repeats this pattern, but with different colors. I wrote the Python equivalent of it, and it fades normally.

Here is the Arduino code:

It turns out that I thought 1024 was the maximum analogWrite() value for the Uno, when it was actually 255. The loop works perfectly; but the lights only dim correctly when the val variables are less than or equal to 255. When the val variables are higher than 255, the colors are at maximum brightness; they can't get any brighter. Hence, no color change when the vals are greater than 255. This is what caused the colors to flash.

To fix this, just replace all occurrences of 1000 with 255 in the Arduino code.

Your script just needs a few changes made to it:

1. It is important to note that the setValues() method accepts as parameter a two dimensional array in the form of Object[][].

You are simply passing it a one-dimensional array, hence the The parameters (number[]) don't match the method signature for SpreadsheetApp.Range.setValues error you are receiving.

In order to fix this, you will have to transform row into a 2 dimensional array and making the following changes

To solve your problem you need to use GVal (Run SourcePos (Writer Text) Text) as the type of ctxGVal instead of GVal Identity.

The rawJSONToGVal function can produce any GVal m so you have to choose the m that is needed by the rendering function, your application of easyRender requires the type Run SourcePos (Writer Text) Text.

vba delete rows of each sheets under multiple conditions

Asked 2021-Jun-08 at 09:14

I please need your help with a code, that from my side I Think is very complicated.

So the idea is :

For sheet 1, if cell in column A <> ws.name then

if cells in column F =55 and cells in column G = any number from 1 to 12 then do nothing

if cells in column F = any number from 1 to 12 and cells in column G =55 then do nothing

else delete all other rows

PS: I have around 20000 rows

Also for Sheet 2, if cell in column A <> ws.name then

if cells in column F =51 or = 53 and cells in column G = 55 then do nothing

if cells in column F = 55 and cells in column G =51 or =53 then do nothing

else delete all other rows

And so on, for each sheet I'll be having different number conditions in columns F & G.

I really hope you can help, I've been struggling with this for a while

Here's the code I tried of exemple in one sheet

You can use .opts() on your plot to change the xlabel.
It's a good way of making your plot look nicer.

convert Bit Array{2} to Array{Bool,1} in julia

Asked 2020-Aug-17 at 23:36

So, as the title explains: Is there a way to convert a BitArray{2} type array to a Array{Bool,1}: type array?

PD: the core of the problem is that I am trying to evaluate an Array{float64,2} with a BitArray{2} and I keep getting the following error: ERROR: BoundsError: attempt to access 20×1 Array{Float64,2} at index [Base.Slice(Base.OneTo(20)), Base.LogicalIndex(Bool[0; 0; … ; 0; 0]), Base.Slice(Base.OneTo(1))]

Thanks in advance!

@Mason EDIT:

So, I have been trying to isolate the outliers present in an array{Float64,2}. I found this two functions online and edited them to allow Array{float64,2} arrays as inputs.

To answer your question, you can use collect to turn a BitArray into an Array, and vec to turn a matrix into a vector:

Answered 2020-Mar-31 at 10:09

While testing the code I realized my mistake. Maybe this will be useful to someone else, so I'll still post the question.

I thought that the reference will wrap a RefObject in the supertype RefObject. This should be fine.

But before this can happen, the react ref that has been created needs to be assigned to the JSX attribute. And here it's the inverse. I'm trying to assign a RefObject to an attribute of type RefObject.

So the typecheck makes a completely valid complaint. This should fail.

The convolution function is basically correct, so the issue is with the input and output format.

Make sure you are reading the image as Grayscale (and not RGB):
