plug in the Arduino
Start the IDE
Select the correct Board and Port
open/write your software
unplug the arduino
press and hold the reset button
plug Arduino back in
Click Upload on the IDE
When the sketch size shows release the button
This MAY help.

Hi liudr, What are you looking for? A free FTP host, or a public site? I host an FTP Server on one of my servers here (UK) - I can provide you with an account if you want.

2 pins - set pin 1 high, pin 2 low - it goes one way
              set pin 2 high, pin 1 low - it goes the other
              set both same and motor stops.

****  DO NOT DRIVE MOTORS FROM ARDUINO PINS ****

you WILL kill your Arduino

Do a search for H-Bridge motor driver, its easy to make your own, or buy a cheap chip based unit if your on a budget.

Goto file - preferences, change font size. ok then restart the IDE (Don't know how to make it BOLD)

Please read the sticky at the top of this forum & also choose a more appropriate section, this is not an installation issue.

When we do them we need :

The hex file
The Fuse settings - pre-flash and post-flash

if (motionVal = 1)     should be  if (motionVal == 1)
if (motionVal = 0)     should be if (motionVal == 0)

The data sheet shows the connection P2 with Rx and Tx marked (connect these to the Due Rx/Tx ) you will also need to connect ground.
56  Using Arduino / Programming Questions / Re: RTC Record Error on: March 11, 2014, 05:48:05 am
It's line 17 of the code you posted ! ! ! !
57  Using Arduino / Project Guidance / Re: How to connect simcom sim900 GPRS+GSM with arduino Due 2012 r3 on: March 11, 2014, 05:09:59 am
On the data sheet I can see P2 and in the photo I can see P2 - The pins are marked with there functions.
58  Using Arduino / Microcontrollers / Re: FTDI with Atmega 328P-PU question on: March 10, 2014, 04:22:26 pm
and connect GND - ok to leave 5V disconnected
59  Using Arduino / General Electronics / Re: Arduino Pro flashes on and off on: March 10, 2014, 09:16:02 am
The regulator chip on the Pro is rated for 150ma (300mA MAX) - so it was crowbarring under load, and resetting your board

Can you take a photo of the sim board from the top, so I can see the labels on the headers please.
