16  Using Arduino / Project Guidance / Stuck on a project on: May 20, 2011, 02:57:59 am
I wanted make a simple bicycle logger. The Hardware would be simple, an arduino one button and one reed switch.
I want the arduino to start logging when i press the button and stop logging when when i press again. The arduino logs how many time the reed switch opens  and the time when it happens so when i go to my computer i can download the data.

Although i have a basic knowledge of arduino coding i dont know how this could be done. Could anyone give me a similar code or some tips on hoe to go about it?
Also, would i need a EEPROM or can the data be stored in the arduino it self?
17  Using Arduino / Project Guidance / Using an old RC car as a cheap wireless remote on: May 15, 2011, 11:09:55 pm
I was wondering if i could use one of those cheap as RC cars as a wireless remote connected to the arduino.
They have 4 channels, and i could just wire them up to the digital pins on the arduino.

Would that be possible?
18  Using Arduino / Installation & Troubleshooting / I am afraid i have done irreversible damage.... on: May 15, 2011, 11:04:47 pm
So, a year or so back, i just got a new arduino and hooked it up with the following digram,
http://i38.tinypic.com/2yzcyf5.jpg


Back then, my electronics knowledge was limited, the mosfet being a IRF540 with a 100Ohm resistor (with the wrong pinout, lol).
Not surprisingly it did not work because the pin out was incorrect
So, i immediately disconnected the circuit but now the arduino does not work, i cannot upload any code to it.
Is there anyway to fix this?

I am having some problems with my Arduino Deumilanove. I cannot seen t install on Windows Xp or 7. I have installed it before on XP but i havent used my arduino for a long time ... Most of the time XP does not even acknowledge  that something has been plugged in and when it does the wizard does not come up. in Windows 7 it does not even show anything is plugged in..
Please help I am A noob At computer and Arduino
Sorry for my english(Not my first language)

Also, i was wondering if i could use the ISCP port to connect to the serial port of my computer and bypass the FTDI chip. If so, where would i find the cable?

do you know any sites that give transistor sample to india?

OK so negative to gnd  and resistor at the gate. How much current is the maximum at gate?thank you for telling me anout that 10v problem. Is it possible to step up the voltage from the arduino?

Sorry for being stupid but is this setup going to work?
The mosfet is an irfz44n and i am going to run the hello world code.The mosfet will be connected to pin 13. Also please send me any sites to help
learn electronics.

Thanks

Would this act the same as a Ping)))?

It appears to be functionally very similar (wth a bit better specifications) but the interface is dramatically different.  Access to the Sunrom device is via TTL serial.  Access to the Ping is via a pulsed pin.



So if i insert this deviece instead of the ping, It would not work?
