| Re: Réalisation d'un afficheur de vitesse pour voiture Posted: 23 Dec 2012 01:40 AM PST Pour répondre à Cristian_R: Le convertisseur fréquence/tension est une bonne piste pour le futur de mon projet, pour l'instant je veux comprendre ce qui ne fonctionne pas dans le prototype. Par ailleurs, l'arduino ne fait que deux choses, de façon rép...             |
| Posted: 23 Dec 2012 01:40 AM PST ok allora farò come dici, grazie mille :-) quello che voglio ottenere nel mio primo progetto è mostrare su un lcd e salvare in un txt nella sd card i seguenti dati: -nr di giri -valore lambda -temperatura gas scarico La mia idea è poi di importare il ...     |
| Re: storing ir remote codes in non-volatile memory Posted: 23 Dec 2012 01:37 AM PST The thing I wanted to do differently was to be able to save codes and play them back without having to know the protocol. In that case, other than altering the quanta ...     |
| Posted: 23 Dec 2012 01:37 AM PST Quote I need to adjust the "low power" to be the most efficient for my antenna No, that does not make sense.Quote it adjusts the qrp capacitor The term low power capacitor is totally meaningless here.What you want to adjust the the...     |
| Re: Clock-Shield (RTC und DCF77 auf einem Shield) *Entwicklung* Posted: 23 Dec 2012 01:36 AM PST Hallo zusammen, ich bin jetzt soweit das der uC des "Shields" 1. Die DCF77 auswertet 2. die RTC beschreibt und wieder ausließt 3. in Power Down geht (wacht alle 8 Sekunden auf) 4. Mit Jumper einstellbar jede Stunde oder ein mal am Tag neu synct. 5. Das...     |
| Re: Trouble using keypad coding Posted: 23 Dec 2012 12:58 AM PST Turn on verbose output during compilation and post what you get.     |
| Posted: 23 Dec 2012 12:58 AM PST Astonishing really (and that's from someone writing this on an iPhone)     |
| Re: Test 1.5v battery mAh with analogread. Posted: 23 Dec 2012 12:58 AM PST While this would definitely suit my needs, I was hoping to get the actual current. That way every few seconds I could see what the current was then at the end I could get an actual mAh reading rather than just a voltage/time number. Could I still do that?     |
| Re: 74HC595 decouple - correct? Posted: 23 Dec 2012 12:54 AM PST You're right. It will work as is, in the original layout. BUT it looks like OP will have the boards manufactured (being double-sided)... and since there's no cost penalty in making your boards look pretty, better designed and more robust... why not? ...     |
| Re: Sensore di temperatura collegato con 10m di filo Posted: 23 Dec 2012 12:52 AM PST Ora quello che io non capisco è come tu arrivi a leggere quella temperatura, vedo che Poolo ti suggeriscono interventi di correzione e probabilmente è giusto, ma for...     |
| Re: Réalisation d'un afficheur de vitesse pour voiture Posted: 23 Dec 2012 12:30 AM PST Le principe du capteur est le bon, Fréquence = k x Vitesse. Mais il est possible que tu loupes un cycle de temps en temps, si l'arduino est en train de faire "autre chose" (calculs dans un autre bout du programme) que de surveiller la broche au bon mom...     |
| Re: Programm / Funktion einmal beim Start ausführen Posted: 23 Dec 2012 12:30 AM PST Ich versteh immer noch nicht warum Code der nur einmal laufen soll nicht in setup() laufen sollte. Das müsste doch gehen.     |
| Posted: 23 Dec 2012 12:27 AM PST Thanks, EEPROM looks promising, any help getting the Searial.read to work? I tried to put together my own version of the blink light if searial.read =='H' sketch, and it seemed like it was not working, but Ill try again tomorrow and see what I can figu...     |
| Re: storing ir remote codes in non-volatile memory Posted: 23 Dec 2012 12:27 AM PST It's also nice having something you can make more of and/or modify/fix. Thanks for the reply. I was thinking that if the bootloader can write to flash, then so could I. Howev...     |
| Posted: 23 Dec 2012 12:25 AM PST im having trouble in compiling this coding, 'Keypad does not a name type'. im already download and placed the keypad library.. anyone can help me?? thank you in advanced... [code]#include <Keypad.h> const byte ROWS = 4; // Four rows const byte COLS = 3...     |
| Re: 74HC595 decouple - correct? Posted: 22 Dec 2012 11:50 PM PST If you look closely at the application and parts used there is nothing wrong with the original layout. for several reasons. I do hope I don't make the PCB experts unhappy BUT there isn't enough current capacity per package to warrant bigger or more Pow...     |
| Re: storing ir remote codes in non-volatile memory Posted: 22 Dec 2012 11:48 PM PST Yes, I've looked at that. The thing I wanted to do differently was to be able to save codes and play them back without having to know the protocol. His code has the raw mode if it can't id the protocol, which is similar to what I'm doing, but he is usi...     |
| Re: calculating error, quickest way Posted: 22 Dec 2012 11:36 PM PST How much did that board cost? Lol I already spent 70$ on this, and I'm finally just in the final proggramming phase working on the gui, but unless someone can figure out that formula perhaps after a certain frequency I will just have it directly chang...     |
| Re: How to get to configuration files on a Mac Posted: 22 Dec 2012 11:34 PM PST Just right-click on the Arduino icon and select "Show Package Contents", and drill down through the subdirectories.     |
| Posted: 22 Dec 2012 11:33 PM PST Thanks Bill. If the worst comes to the worst, they can become stocking-fillers next year. "What, this, Dad?" "It's a crystal, darling" "Cool!"     |
