MRF24WB0MA connection problem with Arduino UNO-R3... Posted: 05 Apr 2013 03:32 AM PDT HI,    I'm buy a MRF24WB0MA WiFi Module. Try to use it on the Arduino UNO-R3(self made board). But WiFi connection problem. Right, MAC address mark the WIFI connection are good.  Do not have th...

Re: Moteurs et courant Posted: 05 Apr 2013 03:31 AM PDT Bonjour à tous, Il s'agit bien d'un distributeur 24 V en courant continu (DC) de référence 520 000 05. Quote S'il est continu il lui faudra 24V et il consommera  I = Puissance/ tension = 1.6 / 24 = 66mA. C'est trop pour un micro il faudra soit un tran...

Re: Praktischer serieller VGA-Adapter Posted: 05 Apr 2013 03:31 AM PDT Besten Dank für den Link, bisher kannte ich nur dieses Teil, wird von der Beschaffbarkeit vielleicht einfacher: http://www.watterott.com/de/Micro-VGA-Mikrocontroller-VGA-Grafikkarte 800x600 schafft der auch (allerdings bei 60 Hz), stellt aber nur 80x25...

Re: can I put the Arduino to sleep in the interrupt routine that wakes it up? Posted: 05 Apr 2013 03:30 AM PDT Re-opening the terminal tool (probably) resets the processor, so they aren't the same thing.

Re: Controling a 12 V Throttle body servo motor Posted: 05 Apr 2013 03:30 AM PDT Quote from: zoomkat on April 04, 2013, 11:47:12 PM If the "servo" in the throttle body is just a brushed motor (per the mention at the Infineon site), then controlling the position with pot might be fairly easy. Does the thr...

Re: Max 7219 with 12v Power Posted: 05 Apr 2013 03:26 AM PDT I am using the MAX for it's intended use, that is a seven segment display. However, I am confused with the lack of current, especially using a 12v, 2A external voltage boost. From what I understand from the data sheets, I should be able to get an outpu...

Re: h bridge a mosfet Posted: 05 Apr 2013 03:25 AM PDT astro dici che l'arduino non può fare il LAP, ma modificando il prescaler PWM si arriva ad un massimo di 60kHz se non erro, e con una NOT fai anche la controfase.. o erro?

Help with picking up best components Posted: 05 Apr 2013 03:24 AM PDT I am looking for a reccomendation of chips for my project which consists of: 31 LEDs (I need to run them on really low current, 5mA is more than enough) 46 pushbuttons 31 potentiometer 4 digital inputs coming from 2 rotary encoders (connected to LM324)...

Re: Problem reading TTL serial data from weather station Posted: 05 Apr 2013 03:24 AM PDT My suggestion is to use the transistor. With a resistor of 10k to the base and 4k7 or 10k at the collector. If the signal from the weather station is very dirty, you could add a diode to the base resistor (if the signal is noisy when low) or change the...

Kindleberry Pi the second #piday #raspberrypi @Raspberry_Pi Posted: 05 Apr 2013 03:00 AM PDT Kindleberry Pi the second, shared by RaspberryPi.org: Did you get a nice shiny new Paperwhite Kindle to replace your old one? (I haven't yet. I'm waiting until the inevitable moment when I drop my Kindle Touch and break the screen; I'm currently on my third.) If you did, you might be interested to learn that when you're not using it to read books or jailbreaking it so you can change the wallpaper, you can use your Paperwhite as a wireless, ultra low-power display for your Raspberry Pi. We featured the original Kindleberry Pi hack from Ponnuki back in September. That hack required cables, and only worked on the old Kindle 3 (the version with the keyboard), not any later versions – plus, it looked a bit odd because to keep the screen in landscape mode you had to turn the whole assembly on its side, so the keyboard was rotated by 90 degrees. The new Kindle 5 (the Paperwhite) has no keyboard, a faster refresh rate, and a backlight that can be turned on in dark conditions. So Max Ogden has polished Ponnuki's original Kindleberry Pi idea, and produced a really tidy piece of kit: a Raspberry Pi with a Paperwhite display, a wireless keyboard and a tiny wireless router. He says: The advantages of the Kindleberry are pretty desirable for me: Week-long battery life: the Pi and the Kindle both have low power ARM processors so you can use any USB charger to power them The Kindle screen is designed for use in direct sunlight The whole setup is small enough to carry around in a pouch inside my normal backpack along with my normal laptop. I work from coffee shops in Oakland and often move around by bicycle during the day — now I can work from almost anywhere and still be at least a little productive…. Read more.

Re: Leonardo Clone 32u4 based board it is not recognized in USB port Posted: 05 Apr 2013 02:57 AM PDT Well except that I tied the AVCCs directly to VCC and that I'm using an oscillator and not a crystal, my (working) schematic is the same. However, I've seen similar dmesg outputs on some of my devices due to soldering problems at the USB connector. Als...

Re: need some help to writing a code Posted: 05 Apr 2013 02:55 AM PDT im sorry, im being unstable like the analog signal ... but its just an idea to solve my problem ... u can see the signals shape ..in the blue one the level is 2 v and its go up and down ....if its more than 2v then pin10 HIGH and if less than 2v then ...

Autonomous boat ferry. Posted: 05 Apr 2013 02:54 AM PDT Hi, A friend of mind is trying to interest me in  a project for him. He lives on an island in a lake, and uses a small electric boat to ferry himself and the family the 100 meters to and from the island. The problem is that they've only got one boat, a...

Re: Binary counting using 12 LEDs Posted: 05 Apr 2013 02:26 AM PDT If you do Code: sum = aNumber; then Serial.print the number and output it to the LEDs in binary and get a different number displayed on each, then obviously one or other is wrong and I know which one my bet would be on.  Do I remember correctly ...
