16036  Using Arduino / Programming Questions / Re: [SOLVED] Servo Motor is not rotating write !! on: April 08, 2012, 03:49:20 pm
It's one of the reasons I have the tag line I do.
My name isn't Dave.

It's called an electrical circuit.

from memory A0 is defined to allow you to use the digital functions 
No reason not to use them for analogue functions.

If you display single digits fast enough, your eye sees them as separate digits.

You've given lightReset the value 2.
How can that ever == HIGH ( aka 1)?

Please help i need this project done ASAP
That's not our problem.

What happens if you light one digit at a time?
Hint: google multiplexed display.

Yes, and you could make the first print a println, and skip the second completely.

i only know how to use serial.print.
So, use that to print the values returned by the rangefinders, before you make any decisions based on those values.

is there anything that i miss?
Did you try printing the raw results?
16045  Using Arduino / Programming Questions / Re: Programming logic using 2 ultrasonic sensor hc-sr04 on: April 08, 2012, 09:17:00 am
No put a delay between taking the a reading and the b reading.
Print raw results.
Figure out what's going on.

. How would I find out the range?
Write a simple sketch to print raw readings.
Point the sensor at the sky.
Point the sensor at something really close.
Point the sensor at the limits of detection.
Note the values.

Look at your "if" and your "while" and ask yourself about punctuation.
16048  Using Arduino / Programming Questions / Re: Programming logic using 2 ultrasonic sensor hc-sr04 on: April 08, 2012, 09:08:31 am
Did you give up on my idea of introducing a delay between pulses?
16049  Using Arduino / Programming Questions / Re: here's a thought... on: April 08, 2012, 09:07:43 am
You mean like a 200kHz long wave signal?
16050  Using Arduino / Programming Questions / Re: Programming logic using 2 ultrasonic sensor hc-sr04 on: April 08, 2012, 09:01:12 am
Thanks for keeping us updated.

no progress..
And pulseIn  still doesn't return an int.
