| Re: Aiuto per calcolare resistenze per LedCube Posted: 13 Jan 2013 01:49 AM PST I found this datasheet about BC237: http://www.datasheetcatalog.org/datasheet/philips/BC237.pdf "NPN general purpose transistors BC237; BC237B" is it correct or not?

| Posted: 13 Jan 2013 01:48 AM PST Quote What I do not know is how to take that result, break it down into two separate digits, and display one number on each 7 se Code: digit1 = number / 10; Have you got resistors in the segments?digit2 = number % 10; You need to mul...     |

| Re: Sämtliche Zeichen eines Arrays um eine Stelle verschieben Posted: 13 Jan 2013 01:45 AM PST Alle Zähler beginen mit 0. Das Array hat zB 9 Elemente. Im Array steht zB 123456789 und Anfangsposition 0 // Abfangssituation bei gefülltem Array nächtes Zeichen A: A23456789 und Anfangsposition 1 nächstes Zeichen B: AB3456789 und Anfangsposition 2 W...     |
| Posted: 13 Jan 2013 01:11 AM PST thanks for the response. I take from your reply that it would be possible for me to control the relay using the RF linkkit. So i can control my relay without wiring directly to the UNO using this method?     |
| Posted: 13 Jan 2013 01:10 AM PST Bonjour. Une nouvelle fois je me tourne vers vous. Ma question est la suivante : Est il possible de completer dynamiquement un tableau de taille inconnue ? [code] float temperature = 0; float delta = 0; int nombre_alarmes = 0; String message_alarme[] =...     |
| Re: [RESOLU]Ajouter un port USB pour clavier Posted: 13 Jan 2013 01:09 AM PST Merci, je pensais la mettre perpendiculaire (90° dans le sens des aiguilles d'une montre) à ce que tu me propose. Donc, je pourrais ne pas couper le GND, mais puis-je laisser 5V USB connecté à 5V Arduino ou dois-je impérativement le brancher à Vin (la ...     |
| Re: PWM at Low Frequencies (.12 Hz-10 Hz) Posted: 13 Jan 2013 01:08 AM PST google translate says: Are you sure that in your log really nothing in it? Or it could also be that you not only see the content? I.e. have you ever looked with a hex monitor? On what I want out: it looks like you are going to write bytes to the fil...     |
| Re: GPS venemittaristoa (Menuvalikko-ongelmaa). Posted: 13 Jan 2013 01:07 AM PST Olen noita analogiportin nappeja käyttänyt "köyhänmiehenkorvikkeena". Että laitan vaikka perusasetukseksi 17" potkurin (siis arvona 17) Ja jokainen napinpainallus antaa arvonsa mukaan sitten lisää nousua. Esim. ylös = 18 alas = 19 vasen = 20 oikea = 21...     |
| Interfacing to circuit which grounds the input Posted: 13 Jan 2013 12:51 AM PST I'm want to interface to a circuit which grounds the input. What it expects is the arduino to hold the line at 5V, and then it has a transistor or similar to ground that 5V signal to give a percentage of speed. It's drawn as attached - the transistor a...     |
| Posted: 13 Jan 2013 12:50 AM PST Ok, I have googled my problem. Found the solution to the digital driver signing problem, and got all my other Arduino boards working just fine. Arduino Diecemila, Mega, Nano etc etc. But when connecting my Arduino UNO it just says: Quote The drivers ...     |
| Posted: 13 Jan 2013 12:49 AM PST Hai ragione. Non l'ho visto. Non so dove é il problema dell'imprecisione. Comunque contare ogni secondo i millisecondi non é la via giusta per migliorare la precisione. È meg...     |
| Posted: 13 Jan 2013 12:49 AM PST Have you seen this library: http://code.google.com/p/rc-switch/ ? I was playing around with it during the holidays and wrote this example: https://github.com/lasselukkari/Arduino-RC-Timer-Switch (mega only)     |
| Re: Aiuto per calcolare resistenze per LedCube Posted: 13 Jan 2013 12:49 AM PST That circuit calls for NPN transistors. BC237B are PNP so not suitable. It would be possible to redesign the circuit and modify the code to use PNP transistors, and then BC237B would be suitable.     |
| Unable to Write Fuses with ArduinoISP Posted: 13 Jan 2013 12:16 AM PST OS: Windows 7 64-bit ISP: ArduinoISP (via USB, COM4) Chip used as programmer: Arduino UNO, ATmega328P Chip being written to: Breadboard, ATmega328P, Internal clock (can't change until I can write fuses) ---------- Hello fellow Arduinoers, I was hoping ...     |
| Re: what kind of Arduino models i need to my project ? Posted: 13 Jan 2013 12:16 AM PST Oh, I forgot... The enclosure will be the hardest thing to find. There are some Arduino enclosures but not very many and rarely does an off the shelf enclosure match your goals exactly. Also, if you're looking for one Arduino to monitor al the sensors,...     |
| IP Adresse auf Display ausgeben Posted: 13 Jan 2013 12:14 AM PST Hallo, hab im Sketch: byte ip[] = { 192, 168, 1, 199 }; stehen, das möchte ich gerne auf dem 20x4 Display ausgeben. Verwendete Lib: <LiquidCrystal.h> Da kommt leider nur mist im moment raus. Gruß Jens     |
| Re: what kind of Arduino models i need to my project ? Posted: 13 Jan 2013 12:14 AM PST What you want to do is really not very difficult. If you're designing a commercial system you can use Arduino parts to prototype it, if you're building a one off then you can just buy the parts and be done. The tricky part is finding compatible shields...     |
| Posted: 13 Jan 2013 12:13 AM PST After googling "arduino 4051" and finding little I decided to try to make a "tutorial" to help get folks going faster. Let me know if you see any problems with the fritzing file, my code or it's comments, really anything. Running out of analog inputs?...     |
