    as a shield to sunlight as shown in the next figures The stable position is when the two LDRs having the same light intensity position A When morning arrives The left LDR is turned on small resistance approximately shorted causing a signal to turn the motor continuously counterclockwise until the two LDRs having the same light intensity again position B As the day slowly progresses position C is reached shortly turning on the LDRs The motor turns clockwise and the cycle continues until the end of the day or until the minimum detectable light level is reached The above figures show that when the sun at the right to the solar panel LDR2 has small value resistance and the other LDR has no light large resistance and a software in the micro controller translate this to signals to control the stepper motor to rotate the panel to the left Circuit description The two LDRs are connected to a bridge and the output of the bridge is connected to a comparator the analog comparator of the microcontroller is used When LDR1 has higher light intensity than LDR2 then the resistance of LDR1 is smaller than that of LDR2 then voltage at AIN0 is higher than that of AIN1 and the output of comaparator is high When LDR2 has higher light intensity than LDR1 then the resistance of LDR1 is larger than that of LDR2 then voltage at AIN0 is smaller than that of AIN1 and the output of comparator is low Then the output of the comparator is used in the UC program to control the stepper motor RV1 variable resistor is used to balance the bridge when the two LDRs having the same light intensities due to the mismatch between the two LDRs The minimum light detectable circuit It s a circuit used to detect the condition when there is no sunlight to turn off the tracking system It uses a summing op amp Circuit it s output is given by Where 1 23V is the internal bandgap reference used by the analog comparator in the UC By calculating the value of V AIN0 and V AIN1 at sunset and adjusting RV2 the output of the comparator can be used to turn on or turn off the solar tracking system Microcontroller program for sun tracking system declaration of variables include mega16 h include delay h char temp unsigned char seq 4 0x10 0x40 0x20 0x80 int i 0 check the sum out ADCSRA 7 0 disable ADC SFIOR 0x08 enable MUX ADMUX 0x02 ADMUX 0xFA selecting PA2 ACSR 6 1 select band gap reference if ACSR 5 1 no sunlight PORTC 3 0 disable sun tracking system else there is sunlight SFIOR 0xF7 disable the MUX ACSR 6 0 disable the band gap ref PORTC 3 1 enable H bridge if ACSR 5 1 rotate counter clockwise while ACSR 5 1 temp PIND temp 0x0F temp seq i PORTD temp delay ms 100 i i 1 4 PORTD 0x0F stop
