@killer
Thanks for asking but unfortunately I never got any further with
a buck system although I am still playing around with arduinos
in different fields. I love playing with these things because
they are so simple to work with.

I trying to build one to track the sun. I got some of the code
working. But its taking me a little time. Im new to them.

@ killer
Yeah I think these arduinos are great....I was going to make a
tracker with one using a old satellite motor and a couple of
LDR`s for the orientation detection but I never did get to
program the micro.....one day ;D
Keep playing with the code and you will get to what you
need....I am still learning the code too !!!
Been playing with a GPS module and a 0.96" oled screen....what
fun this is :D

using leds to test my idea, here is my code.
// These constants won't change:
const int analogPin = A0; // pin that the sensor is attached
to
const int analogPin2 = A1; // pin that the sensor is attached
to
const int ledPin = 13; // pin that the LED is attached to
const int ledPin2 = 12; // pin that the LED is attached to
const int threshold = 3; // an arbitrary threshold level
that's in the range of the analog input
const int threshold2 = -3; // an arbitrary threshold level
that's in the range of the analog input
int Value;
void setup() {
// initialize the LED pin as an output:
pinMode(ledPin, OUTPUT);
pinMode(ledPin2, OUTPUT);
// initialize serial communications:
Serial.begin(9600);
}
void loop() {
// read the value of the potentiometer:
int LeftReading = analogRead(A0); // Read left Cell
int RightReading = analogRead(A1); // Read Right Cell
Value=(LeftReading-RightReading)/10;
if (Value>3) Value=10;
if (Value<-3) Value=-10;
/*
Limits the maximum difference between -10 and + 10
*/
// if the analog value is high enough, turn on the LED:
if (Value > threshold) {
digitalWrite(ledPin, HIGH);
}
else {
digitalWrite(ledPin,LOW);
}
if (Value < threshold2) {
digitalWrite(ledPin2, HIGH);
}
else {
digitalWrite(ledPin2,LOW);
}
// print the analog value:
Serial.println(Value);
delay(1); // delay in between reads for stability
}

@ killer
Your code is getting there....learning by your own mistakes is
the best way to learn in my opinion.
only comment I could make is that A0 and A1 have been given a
constant so lines 20 and 21 could be changed to ...
[code] int LeftReading = analogRead(analogPin); // Read left
Cell
int RightReading = analogRead(analogPin2); // Read Right
Cell[/code]
Fantastic to see someone else playing with arduinos.
My personal idea for the detection was to use 2 LDRs in series
between 5v and 0v then sense the voltage between the 2 which
should return a value of about 512 on the analogue pin once the
solar panel is perfectly aligned to the sun.
Great work and thanks for sharing your code.
