Programming Questions / Re: Bluetooth Fernbedienung
Last post by Goramig - Today at 10:56 am
English:

Hello everyone.

To come to the point i want to build a bluetooth remote.
I have the HC-05 bluetooth adapter (I'm not very skilled in Arduino)

I need buttons for:
-Power
-Rauf
-Runter
-Links
-Rechts
-Lauter
-Leiser
-OK
-Zurück

My question is, after i have defined the buttons how can i read them and give them the right function?

Thank you for the help

Goramig!

Inhalt der zip-Datei in das Lib-Verzeichnis Deiner arduino-Installation, den Verzeichnisnamen kürzen auf battery-tester. Dann IDE neu starten.

Was passiert?

Ach ich seh grad: das ist ja gar keine Lib  :)
Kommt davon, wenn man zu schnell über den Text huscht ...

You have posted a code snippet.  Code snippets can be a problem because they usually omit important information.

I would guess that the variable s is declared as String.  String is problematic and to be avoided on small memory devices such as most Arduinos.  String can lead to fragmented memory and hangs. C strings (text terminated by a null character) works well and avoids most hangs.

I am surprised that this even compiles:

Code: [Select]

          Serial.print F("Dumping log file size: ");        // log.txt is valid for sending to browser


I am away from the Arduino IDE and cannot try this on my mobile device.

Project Guidance / Re: Servo control with joystic...
Last post by FLCFLC - Today at 10:54 am
yes wawa, Thank you, everything you describe makes complete sense and has already taught me so much and still are.
Yes those joystick modules dont have a full swing,
But my idea was to be able to control a robotic arm the same way an excavator machine controls work, But using a 6 axis robotic arm.
I have made everything by hand exept for using a cordless drill.

Now realising joysticks dont have a full swing, Im going to start with  potentiometers now just to understand it better before upgrading to something a little more advanced.

MKRVIDOR4000 / Re: [SOLVED] Details for the E...
Last post by DarioPennisi - Today at 10:53 am
ok, so from what i understand you want to filter velocity which would be the differential of the encoder output. any FIR filter would add a delay in the measurement so a long filter will probably delay too much. what you want to do is absolutely and easily feasible in the FPGA but at the moment the web UI is not ready so you won't be able to do it alone if not fiddling with RTL directly.
since i am working on the motor library any input on it is appreciated so please let me have your wildest dreams and let's see what can be done.
so far we have:
- PWM (the current one should be fine... it has fixed frequency on all channels and variable phase/duty per channel)
- encoder (we just need to parametrize it differently, maybe, since if loop is handled in FPGA 16 bits may be more than enough
- FIR
- PID
- limit switch input (to reset absolute encoder values)
- I2C bus master (for temp sensors and other devices to monitor status)
- HDMI output (for user interface)
- a mechanism to dynamically link everything

what else?

Sollte es eine Bibliothek mit dieser Bezeichnung überhaupt geben, wisst ihr das? Oder liegts vielleicht daran, dass diese Bibliothek garnicht existiert?
Wenn Du sie nicht gefunden hast, dann hast Du sie auch nicht installiert.
Ich habe nichts zu dieser Lib gefunden.

So your suggestion is to give another power source for the relay module and not the arduinoUno. Am i right?
Yes. Be careful on connecting grounds, for you need the optocoupler input to be referenced to the arduino. Better if you send a link to the board (or picture).

Software / Re: Spiegazioni per millis()
Last post by SukkoPera - Today at 10:52 am
Tu a capire non ci stai neanche provando. La prova è che rispondi ai miei messaggi subito dopo che li ho scritti, senza invstire un po' di tempo a RAGIONARE e a tentare di arrivare ai concetti a cui sto cercando di portarti.

Prendi un foglio e fai 3 colonne, in cui scrivi.
1. millis() a intervalli di 1 secondo dall'istante 4000 in poi.
2. 4000
3. differenza delle prime 2 colonne.

E vedi cosa succede quando superi l'istante 7000.

Questa è l'ultimo suggerimento che ti do, il resto sta a te.
