need block forprogramming with arduino uno,hc05 ,hcs04

[Abdullah Alvi]

someone please help me in making this arudino un0, hc05 and ultasonic distance sensor to show distance and red ,orange , green bars. thanks in advance

Post your AI2 blocks.

In the meantime,

Use println() to separate messages when you transmit.

Set Delimiter = 10 in BlueTooth Designer.

Check for Bytes Available > 0 in blocks,

but then request -1 bytes to get only full  messages.

See https://groups.google.com/forum/#!msg/mitappinventortest/lVaCyAeWm_4/ADjvy05wAwAJ attachments.

Also, to get colors in Ai2, do the decision on AI2,

not on the Arduino.

If distance < 30 then color =  ...

else if distance < 100 then color = ...

else color = ...

end if

Dear these are my blocks

[Abdullah Alvi]

this is my main screen interface

[ABG]

See the Debugging section of FAQ

https://groups.google.com/forum/#!msg/mitappinventortest/wqJin0qO8M0/8xUafdROAgAJ

for how to debug using Do It.

sir waiting for humble reply 

[ABG]

In this type of app, it is important for the person

who wrote the Arduino code to read  the AI2 blocks,

and for the person who wrote the AI2 code to read the Arduino code.

This did not happen here.

The 2 programs differ in how they think the messages should be formatted

and how to deal with the formatting.

The AI2 blocks do not check the messages to see which message is carrying the distance.

They also look for distance values next to the Red color,

which does not even need to be sent if the color choice logic is in AI2.

Also, Delimiter advice has been ignored.

Also, no attempt at use of the Companion has been made to see the incoming data stream.

will you please do a little effort to correct this code or make application that could help me.

thanks in advance

[ABG]

Pardon me, I must go do something more productive at this time.

I relinquish this thread to any one with more patience.

We try to help you to solve your problems yourself, we are not here to write your app for you, which would be anyway impossible because we do not have the same hardware.

ABG gave you plenty of tips how you could improve your code. If you have a problem doing so, the ask a specific question on your specific problem.

Cheers, Ghica.
