write a well comment on the ATMEGA 328P -UP microcontroller of the sun tracking solar panel below:

#include  Servo myservo; int ldr1 = 4; int ldr2 = 5; int val1; int val2; int pos=90; void setup() { myservo.attach(11); Serial.begin(9600); myservo.write(pos); } void loop() { val1 = analogRead(ldr1); val2 = analogRead(ldr2); val1 = map(val1, 0, 1023, 0, 180); val2 = map(val2, 0, 1023, 0, 180); if(val1 > (val2+50)) { if(pos<180) pos=pos+1; myservo.write(pos); Serial.println("backward"); delay(10); } else if(val2 > (val1+50)) { if(pos>0) pos=pos-1; myservo.write(pos); Serial.println("forward"); delay(10); } }
