App for teaching the visually impaired to cook

wait im still confused about what Label1 and Label2 does. Whats the difference between label 2 and label 3/4. also whats the purpose of label1? isnt global information the same thing

The purpose is that you learn how this works and you can do your app....

The labels are only to show you how this need to understand this if you want to be able to do your app...

?? so you mean Label1 and Label2 have no purpose??? im so confused

No label has any is an app for blind people...the only purpose of the labels is so that you can see if what you do is right, understand what you do and debug the app.

If you don't understand how to do that, how are you going to split the recipe and Speech the ingredients?

If you understand that you can fix your aia...and to fix what are you doing wrong in, for example, Initialize block.

may i ask what does initialize global intervalRecipe to 0 mean? im pretty sure i copied it from your file

If I don't remember bad it was the time (minutes) of the steps of the be able to set a timer before...but I think you can leave that aside for now...until you get there.

wait can you tell me which part is wrong with my blocks now? i dont want to directly copy but I really have no clue how to debug it

take your code and do the same than the different steps into different be able to see what you are doing with the different blocks...I suppose that with each block you place you want to achieve something, right? then place a label after each block.. place the result, and then move on to the next one.

hmm why do i need to put a label after each block?? sorry but im still very confused (now u know why i want to open new posts xD)

How are you going to find out what is wrong in your code? I have placed 4 labels (later I can remove them) but the 4 labels let me know:

  • Label1: If I was receiving the scanned data correctly.
  • Label2; If my split block was working like I wanted
  • Label3: If I could have my ingredients in a piece so I can use them in a TextToSpeech block to read the ingredients
  • Label4: If I could have my recipe (steps) in a piece to follow working with it to separate the different steps...

If any error in any of those labbels I can fix it and check it again until I get the result I want.

You have not any label so what do you know? Only that your app doesn't work like you want...

wait how is it related??

im sorry but im still very very confused about how labels and debugging are related

labels allow you to see the result of the blocks you are using...but don't need to use you know what your block "split" is doing in Screen_Recipe.Initilize? Is it doing what you want it to do?

your split block is not splitting...paste a screenshot of you split block

You could try something like this:

The entire recipe is contained in a json:

{"title":"Hollandaise Sauce", "description":"A classic rich, creamy sauce", "servings":"Serves 2-4","ingredients":["125g butter","2 egg yolks","Β½ tsp white wine vinegar or tarragon vinegar","squeeze of lemon juice","pinch of cayenne pepper"],"method":{"STEP 1":"Melt the butter in a saucepan and skim any white solids from the surface. Keep the butter warm.", "STEP 2":"Put the egg yolks, white wine or tarragon vinegar, a pinch of salt and a splash of ice-cold water in a metal or glass bowl that will fit over a small pan. Whisk for a few minutes, then put the bowl over a pan of barely simmering water and whisk continuously until pale and thick, about 3-5 mins.", "STEP 3":"Remove from the heat and slowly whisk in the melted butter bit by bit until it’s all incorporated and you have a creamy hollandaise. (If it gets too thick, add a splash of water.) Season with a squeeze of lemon juice and a little cayenne pepper. Keep warm until needed."}}

Obviously, I have not included a recipe picker....

For a recipe like this:


Step1. Put the water in the pot
Step2. Boil the water
