Re: programmare il 644 ... ma come???? Posted: 22 Dec 2012 01:30 AM PST Quote from: Michele Menniti on Today at 03:24:38 AM anche su Arduino le indicazioni "tx/rx sono riferite all'ATmega328 e NON all'8u2, ecco perché anche in quel caso i collegamenti vanno fatti diretti. Esatta...

Re: Problema con motore a spazzole Posted: 22 Dec 2012 01:27 AM PST la mia non doveva essere una critica. si, che il mosfet va' bene

Re: USB Keyboard input Posted: 22 Dec 2012 01:27 AM PST could you post your sketch?

Re: Runing fan with parallel port Posted: 22 Dec 2012 01:26 AM PST So are we using a PC's parallel port ?    and you need code to run on the PC ? OK, so this used to be done.   Borland C++ had a nice list of code to run like this. BUT : windows came along, and the parallel port is now  'protected' by the windows soft...

Re: Automated greenhouse project Posted: 22 Dec 2012 01:20 AM PST PeterH has covered it all really. A few additional points - if you're going to use arduino, stick with the Uno if possible: it'll cover your initial needs, your students are bound to destroy some and the Mega is pricy. While you're developing, conside...

Pong Clock Posted: 21 Dec 2012 09:49 AM PST   This is an original way to build custom digital clock. Thank [mrnick1234567] to send us this project, I suggest you to see the [video] to understand better the capabilities of this clock. This is a year or so old now, but I though you might like to feature it. It's a clock that plays the game pong to tell the time. It uses a couple of cheap LED matrix panels an Arduino and clock chip. As the author says, all the instructions are on the [website], "..and quite a few people have build them / modified my code to add other features." We hope they will submit their "mod", I would be glad to post them in the blog.

3D SparkCube with Arduino(s) Posted: 21 Dec 2012 03:36 AM PST   Here an amazing project. It's a 3D projector "homemade" with Arduino. Many Arduinos and lot of LEDs RGB. We build a LED cube with 4096 LEDs powered by 16 arduinos. It can show 3D animations, words, and just about anything else we want. It stands about 6 feet tall including the base and has over a mile of wire connecting it all together. The full build log and images are hosted on the [website]. Thanks [tbennett] for submitting it

Relay curcuit not switching on Posted: 22 Dec 2012 12:58 AM PST Hi everyone, I am new to the arduino world. I want to make a simple relay switch that sits ontop of a cord connected to my wall (220V). I want it, on my command using arduino, to turn on and thus turn on a light. I have a Compact fluorescent lamp as my...

Re: Asynchronous SeaTalk Posted: 22 Dec 2012 12:54 AM PST Many thanks to Nick and John for their contributions to SeaTalk communications on Arduino. After reading this forum thread, I was able to wire up the interface circuit and have a functioning system in just a couple hours. You guys have saved me days of...

Re: Board Application Posted: 22 Dec 2012 12:52 AM PST Quote from: PeterH on December 21, 2012, 10:17:12 AM If the thrust vector is offset to either side then the vessel is accelerating in roll and you probably want to try to bring it back into balance. That's why I said us...

Re: Can't get stepper motor to spin with library... Posted: 22 Dec 2012 12:52 AM PST It would help if you said what you actually want. A stepping motor has maximum torque when it is stopped, the so called holding torque. The faster it moves the lower the torque until a point where it is not able to even over come its own mass, this is ...

PHP et arduino ethernet shield Posted: 22 Dec 2012 12:44 AM PST Salut à tous, je suis en train de développer un programme en PHP pour l'utiliser avec mon ethernet shield. Seulement, comment le "connecter" à l'ethernet shield pour pouvoir, par exemple contrôler la luminosité d'une led ? Toute aide est la bienvenue. ...

Programming an arduino with an arduino (Bootloard loaded already) Posted: 22 Dec 2012 12:33 AM PST Hi all. I'm developing a board for use with the Raspberry Pi. It has an atmega 328 installed with the Arduino boot loader already loaded. I want to test the arduino side before I install anything else. I have no usb access on the dev board. Only rs232 ...

Re: AVRisp to ATtiny2313: is my Nano v3 bricked? Posted: 22 Dec 2012 12:30 AM PST AVR ISP is a project included with the Arduino IDE that allows users to program other microcontrollers using their Arduino similarly to an In-System Programmer. It essentially treats the Arduino, usually connected via USB, as a legitimate programmer fo...

Re: uso particolare 7805 Posted: 22 Dec 2012 12:26 AM PST Se hai un max di 14,7V ti conviene usare il partitore da 2k + 1k: in questo modo non rischi di superare i 5V. Per Michele: ma come, io do la soluzione e tu ti freghi il karma?

Re: programmare il 644 ... ma come???? Posted: 22 Dec 2012 12:24 AM PST Quote from: Paolo S on December 21, 2012, 03:27:23 PM si.. confermo le letture rx e tx, come sotto, lette direttamente dalla serigrafia del convertitore .... mi sono guardato il link del Convertitore, si basa sul CP210...

Problema Arduino + LM35 e LED... Posted: 21 Dec 2012 11:54 PM PST Ciao a tutti, sto realizzando un termometro con Arduino e una LM35... Vorrei fare che una volta superata una soglia di temperatura mi si accenda un LED... Il codice che utilizzo è questo: [code]int potPin = 0;                             //input read p...

Transceiver Power Down vs Completely Off Posted: 21 Dec 2012 11:53 PM PST So I am using a nRF24L01+ transceiver in my project and I realize it has a power down mode that helps it save power in battery settings. However, if my arduino is running at 3.3v, then can I not simply power the transceiver through a digital I/O pin an...
