1  International / Español / Re: Utilizar ICSP de de Arduino UNO para programar un ATMEGA 168 desde AVR Studio on: January 15, 2014, 12:18:05 am
hola
Tengo alguna duda. Comentáis que el arduino emula un STK500,  (cargando con el ejemplo "ArduinoISP", entiendo).  Entonces a efectos practicos,  podría usarse como programador el Atmel Studio ? Lo habéis probado ?
Muchas gracias por vuestro tiempo.
2  Using Arduino / Networking, Protocols, and Devices / Two sensor with SPI on: December 10, 2013, 08:20:14 am
Hello
I have completed the assembly of two devices in the spi bus (arduino Uno R3). Regardless work well. When i connect together the temperature sensor stops working (disconnecting the miso sd working properly.) The connections are described in the forum. 13-CLK  12-MISO 11-MOSI and 8-SS (SD) and 9- SS (thermocouple).  The sensors are

thank you very much
3  Using Arduino / Microcontrollers / After change the micro arduino don't fund on: October 14, 2012, 11:35:09 am
My arduino uno not work very well to do some actions, (but i could program it ) So I decided to change the micro. Buy two ATmega328P-PU with the loader on ebay . I put one of the new micros  and it did not found appeared the message  "vrdude: stk500_recv (): programmer is not responding" I put the original  and not let me load programs and put me the same error. Now arduino, does not work with any processor, that could have happened? motherboard is broken?  thanks
4  Using Arduino / Motors, Mechanics, and Power / Short power with more than 2 servos on: September 12, 2012, 11:39:09 am
shorted source power with more than 2 servos. I connect the servos to the Arduino board. Servos and arduino are powered by an atx pc power.(Servos power are conect directly to de source power). when work only one all found well but when work more than one the source power is shorted. I put zener and capacitor in parallel at the input paraleo if any problem was a power surge.. I can't do nothin more

thanks Grumpy_Mike , but another question, how do I connect these capacitors?

Is a PC power, more than 20A for 5 volts. thanks

The servos are connected to an external source, and share the mass with arduino. Arduino handles only single pulses to move the servo.
8  Using Arduino / Motors, Mechanics, and Power / problem connecting more than one servo on: December 05, 2011, 08:21:46 pm
I have a problem to handle more than one servo. I have three servos, if I connect only one at any pin OWN work properly. But when I try to connect more than one servo simultaneously (each pin in his OWN) the source is shorted and everything stops working. What can be the problem. Thanks for everything.
