| Re: trying to parse a serial string with strange results Posted: 19 May 2013 03:17 AM PDT Thnx for the suggestion. I allready constructed a other solution:[code]float convertDegrees(String readString) { char buffer[readString.length()+1]; // make sure thers always room int i = 0; while (i <= readString.length() -1) { if (i>readStrin...             |
| Posted: 19 May 2013 03:17 AM PDT Con 70€ non fai concorrenza al RaspberryPI. In ogni caso ciò che conta è la comunità che ci sta dietro, l'Arduino ha avuto successo proprio per questo.     |
| Re: [CAD] Creare schedina 5 bottoni per Arduino Posted: 19 May 2013 03:15 AM PDT io userei il discorso del doppio contatto se vuoi avere un circuito pulitissimo, senza andare a toccare A0, specialmente se hai gia' i pulsanti perche' non usarli ? ...     |
| Posted: 19 May 2013 03:15 AM PDT Zet hem maar op iets van 1-10V en meet de volt erover heen. Door de lage weerstand van de stroom meting gaat je verhaal niet meer op. I = U / R.     |
| Posted: 19 May 2013 03:15 AM PDT Io sapevo invece che era possibile farlo anche con processori non previsti per il calcolo parallelo, c'erano delle estensioni per Linux per far cooperare più macchine anche di diversa potenza, collegate via ethernet. L'hanno fatto anche con il Raspberr...     |

| Re: Arduino hall effect and dc motor Posted: 19 May 2013 02:54 AM PDT i will make this circuit, and then it will be controlled by arduino but the source will be exernal if i understood well. right?     |
| Re: Problema di bouncing con pushbutton Posted: 19 May 2013 02:54 AM PDT turbodede, quando risolvi un problema, specialmente se sei stato aiutato, e' giusto dire come. credo il tuo errore era qui Code: if(valore!=valoreDopo) { clik=1; } ad 1 devi settarlo quando sono uguali, non quando sono diversi, fermo rest...     |

| Posted: 19 May 2013 02:26 AM PDT Hi to all. Sorry for my bad english.... I have an ESC model SP-03018. i need to control it whit arduino UNO. I have tryed a lot of programs but they not work...someone can help me??     |

| Arduino hall effect and dc motor Posted: 19 May 2013 02:24 AM PDT Hello, I want to do this circuit, a hall effect sensor will measure will measure the returns of a small tire then arduino take the returns measured per minute and with the speed measured, do some calculations and the result will be the speed of a 12 d...     |
| Re: 2N2222 Transistor with LEDs Posted: 19 May 2013 02:24 AM PDT Quote You need to connect a resistor into the base - between the arduino output and the base of the transistor.The value of 1000ohm would be ok.. How did you determine 1kohm?     |
| Re: How does audio travel through you? Posted: 19 May 2013 02:23 AM PDT Quote I assume the amplifier is build into the computer speakers no? Yes.An amplifier has a high input impedance. Therefore when you add the resistance of your body in series with the signal it makes very little difference to the signal beca...     |

| I2C slave send data from multiple sensor to the Master Problem! Posted: 19 May 2013 01:45 AM PDT Hello! I have successfully accomplished to send data from one sensor over I2C from the slave to the Master (I used a light sensor). But for my project I want to send from the slave data from more than one sensor. For that purpose I have p...     |
| Posted: 19 May 2013 01:34 AM PDT Hey folks, I have a light sensor i need to get analog readings from. I have set the serial to being in the sketch, connected the sensor to analog input but when i use serial monitor it shows nothing. The sensor is working fine - but i have to just gue...     |
