oke thank you very much for your usefull comment paulS,
my problem is can i read the ldr value int the same time with servo movement??
is there any way to do both of them without unmark serial println for ldr?

oooh i see ..
is there any solution for this problem paulS ??

iam sorry paulS i dont understand about your reply..
can you explain me with more details explanation about my problem??

Ooh, i see paulS. I have another question.
When my servo sweeping based on ldr, i do serial println on my ldr in the same time, why the servo movement going to slow when i do this? But when i unmark the serial println the servo movement going back
to normal..



Anybody help me please with the schematics to charge and measuring battery on my
arduino..

Thanks paulS
can you help me with the schematic? How can i put the solar panel to charge the battery and measuring. battery on my arduino uno r3?

Rob tilaart thank you very much..
On your 6 channel voltmeter, how you get the formula of float voltage? Explain me please..
And how do i put the battery on arduino with solar panel? Can i use digitalpin for my voltmeter?

paulS
I think my solar panel has 9V supply, how do you think?

Hai rob tilaart thank you very much..
But why the baudrate set so big? I usualy set for 9600, and i have use my analogpin for ldr and potentiometer, do you have another way?

paulS
What do you mean with real source of power?

Thx for your usefull comment paulS, can i make a voltmeter just with an arduino?
So what i have to do to move servo without 9V battery?

hi ..
I just finished with this project ..http://www.instructables.com/id/Self-Sufficient-Arduino-Board/?ALLSTEPS
but why when i loose the power of the computer and run my project, the servo motor does not move according to my previous projects?? http://www.instructables.com/id/Arduino-Solar-Tracker/
I combine these two projects into one project and run it ..
the question is
why the project is not going to use batteries??
How can i read the voltage of battery(battery indicator)?
I use ultra accuplus 9V battery or eveready 9V..
thanks in advance

Hi krodal thx for your reply.. But i dont unserstand any electricity.. Can u give me the arduino scheme with solar panel and rechargable battery? I use accuplus as a battery and the spec is ..
Ni- MH 9v, 150mAh..

hi everybody ..
i almost done with my first project ..
but i had no idea about this things ..

i want to charging any battery with my solar panel and my arduino board,,
but i dont know what kind of battery that i have to use, and how the arduino circuit and solar panels that can charge batteries that i use..

sorry for my ignoreance ..
but please someone give me any tutorial ..

hai dhenry ..

i'm sorry i have just read your reply, but actually, i can't understand about your answer, it cause i'm just a nubi on electronically ..
can you give me more explanation?

well,,
the next question is, can i put 12 ldr on my arduino board without breakout board or another  additional board??

i have just read this link http://learn.adafruit.com/photocells/using-a-photocell  but i have not yet solve the problem, why my ldr value always give me a "zero value" ??
and here's the code
Code:
int photocellPin = 2; // the LDR and cap are connected to pin2
int photocellReading; // the digital reading
int ledPin = 13; // you can just use the 'built in' LED
void setup(void) {
// We'll send debugging information via the Serial monitor
Serial.begin(9600);
pinMode(ledPin, OUTPUT); // have an LED for output
}
void loop(void) {
// read the resistor using the RCtime technique
photocellReading = RCtime(photocellPin);
if (photocellReading == 30000) {
// if we got 30000 that means we 'timed out'
Serial.println("Nothing connected!");
} else {
Serial.print("RCtime reading = ");
Serial.println(photocellReading); // the raw analog reading
// The brighter it is, the faster it blinks!
digitalWrite(ledPin, HIGH);
delay(photocellReading);
digitalWrite(ledPin, LOW);
delay(photocellReading);
}
delay(100);
}
// Uses a digital pin to measure a resistor (like an FSR or photocell!)
// We do this by having the resistor feed current into a capacitor and
// counting how long it takes to get to Vcc/2 (for most arduinos, thats 2.5V)
int RCtime(int RCpin) {
int reading = 0; // start with 0
// set the pin to an output and pull to LOW (ground)
pinMode(RCpin, OUTPUT);
digitalWrite(RCpin, LOW);
// Now set the pin to an input and...
pinMode(RCpin, INPUT);
while (digitalRead(RCpin) == LOW) { // count how long it takes to rise up to HIGH
reading++; // increment to keep track of time
if (reading == 30000) {
// if we got this far, the resistance is so high
// its likely that nothing is connected!
break; // leave the loop
}
}
// OK either we maxed out at 30000 or hopefully got a reading, return the count
return reading;
}
15  Using Arduino / Sensors / putting 12 ldr on my arduino uno board on: December 03, 2012, 09:00:49 pm
Hi everyone.
I have a project which i have to put 12 ldr on my arduino board, all i know is the ldr should put on analog pin(A0-A5),,
The question is can i put the ldr in digital pin? And anybody can give me sketch of arduino use a digital pin for ldr??
Thx before.. smiley
