| Re: Blown Caps in 0-30v 0-10a bench supply repair Posted: 27 Dec 2012 01:19 AM PST Here is the circuit diagram that I have found from Chinese website, it may be not the same as what you have but you got an ideas of how this type of power will look like. And here is the manual explain the working of the power supply almost the same ...             |
| Re: 2 servos (or any functions) operating simultaneously? Posted: 27 Dec 2012 01:19 AM PST Quote I found a routine here <http://scolton.blogspot.com/2010/07/arduino-interrupt-driven-servo-routine.html> that uses PWM, resets one of the board's timers, and uses interrupts to control the servos That's exactly what the Servo library d...     |
| Re: 2 servos (or any functions) operating simultaneously? Posted: 27 Dec 2012 01:17 AM PST Thank you for the tip, Upon examining 'blink wo delay', it appears that every time the defined interval is reached and the led blinks, the previousmillis is redefined to be currentmillis so that the iteration gets continually restarted, thus creating a...     |
| Posted: 27 Dec 2012 01:13 AM PST Also ich bezweifle, das folgende Schleife überhaupt durchlaufen wird: Code: for ( pos2= 90; pos2 == 45; pos2 -= 1) Der zweite Eintrag im Schleifenkopf ist eine Abbruch-Bedingung. Die Schleife wird solange durchlaufen, bis diese Bedingung "false"...     |
| Re: DS3232 + PLL for a more accurate clock? Posted: 27 Dec 2012 01:12 AM PST I did not want to correct the crystal. I wanted to replace it. The idea would have been to have a 32768 Hz signal from the DS3232 (accurate to 2 ppm). Then to divide it by 32 to arrive at 1024 Hz. This should be phase locked to a signal that is divided...     |
| Re: circuito per modulo camera ls y201 Posted: 27 Dec 2012 01:02 AM PST Ok, ma anche in questo caso non dovrei vedere caratteri strani o cose prive di senso? Io non ricevo nessun output e dubito fortemente che il modulo riceva i miei input... Inoltre, ho trovato nel sito linkato uno sketch per arduino, quindi penso che sia...     |
| Re: Blown Caps in 0-30v 0-10a bench supply repair Posted: 27 Dec 2012 01:02 AM PST With all due respect, since you seem to be somewhat lacking in knowledge on what a power output transistor looks like, then your chances of identifying the problem are pretty low. Without a circuit dagram, someone who really knows what they are lookin...     |
| Re: 8x8x8 multiplexed LED cube with an Arduino Mega 2560 Posted: 27 Dec 2012 01:00 AM PST I've juts realized that the fact that driving the LEDs with MAX7219 chips in such a simple and elegant fashion has a price to be paid during construction of the LED cube. If I drive each horizontal plane of 8x8 LEDs with one MAX7219, I'll need to have ...     |
| Arduino as an impersonated flash drive Posted: 27 Dec 2012 01:00 AM PST Greetings all! I'd like to plug my Arduino into a computer and have it impersonate a flash drive. Now you may be asking yourself, "why on earth would you want to do that?!" In a nut shell, my long term goal is to plug the arduino into a digital pict...     |
| question a propos de la lib Wire et de l'I2C Posted: 27 Dec 2012 12:58 AM PST Bonjour, pour mon projet de géné HF, je veux utiliser le bus I2c de mon Teensy en mode esclave, j'ai bien compris le pb des adresses, cependant on ne parle pas de la vitesse du bus. le maître peut fonctionner en 100Khz, 400 Khz et 1 Mhz, comment fait-o...     |
| Failed Spiral Light Prototype #3dthursday Posted: 27 Dec 2012 01:00 AM PST While it doesn't always work out, sometimes it is still worth quickly implementing your idea, producing a prototype, and trying it out. I think too often we just share our completed projects and forget to remind people that desktop 3D printers can be low-cost rapid prototypers, a means to quickly get your model in the physical world so that you can get real world feedback. From John Chan:
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don't forget the countless LED projects that are possible when you are modeling your projects in 3D! The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you've made a cool project that combines 3D printing and electronics, be sure to let us know, and we'll feature it here!     |
| Re: URGENT!! Aquaponics System w/ monitoring using Time.h and BlinkWithoutDelay Posted: 27 Dec 2012 12:18 AM PST have you tried this? I did but was having problems not calling alarms from eprom but I dont have a network sheild was using serial commands and I'm also using a arduino mega 2560 so here's the link[url=http://practicalmaker.com/projects/macroduino-proj...     |
| Re: trovare isctruzioni per 485 inverter aurora PVI12.5 Posted: 27 Dec 2012 12:18 AM PST Ciao 79flavio79 Hai la descrizioni del inverter per interpretare i dati trasmessi o richiedere dati? L' Arduino DUE non é la scelta opportuna. È meglio usare il Arduino UNO perché funziona a 5V e perché la sua potenza di calcolo basta per l' applicazio...     |
| two way comms device for voice Posted: 27 Dec 2012 12:16 AM PST I am looking to undertake a project and the arduino looks suitable for prototyping the feasibility. I want to have two way communications between two/three people using voice. Range is 150m max. From research it seems that the best way to do this woul...     |
| Posted: 27 Dec 2012 12:10 AM PST I found the forum topic where I first published the previous code. This particular message http://arduino.cc/forum/index.php/topic,131579.msg991064.html#msg991064 shows how to use the "class version" of the code.     |
| Re: Peltier-based dehumidifying cabinet Posted: 27 Dec 2012 12:06 AM PST Quote Has a long life, with Mean Time Between Failures (MTBF) exceeding 100,000 hours I don't see you wearing it out really fast you can lower the voltage or current to maintain temperature. Maybe PWM is not the name to use more like turn it o...     |
| Re: Installare iniezione elettronica indiretta con l'aiuto di Arduino Posted: 27 Dec 2012 12:00 AM PST Salve, mi permetto di intromettermi in questo post vista la mia esperienza in campo motoristico e specialmente in gestione motore. Chiarisco alcune cose: 1-gli inni...     |
| Posted: 26 Dec 2012 11:57 PM PST Grazie mille, mi era sfuggito, ora provo!     |
| Posted: 26 Dec 2012 11:56 PM PST Yes, I'm following those charging recommendations. It's too bad the battery requires such a precise voltage. Maybe I can cheat and take it up to 3.5 or even 4v at low current? I'd rather not though, and of course it says right there that I shouldn't. @...     |
| Arduino bluetooth to Android tablet Posted: 26 Dec 2012 11:51 PM PST I can use my laptop to receive data from the Mega via Bluetooth. This is done using RealTerm. I would like to do the same thing with my Android ICS tablet. The tablet can see linvor, but none of the apps that I have tried will talk to it.     |
