SunTracker - working

2/11 got everything mounted Sketch written 021125_suntracker_copy_20250211151900 seems to be working except LRR reasd zero 2/12 added 10k resistors to each let Connect one leg of each LDR to the 5V pin on the Arduino. Connect the other leg of each LDR to an analog pin on the Arduino: Top-left LDR to A0 Top-right LDR to A1 Bottom-left LDR to A2 Bottom-right LDR to A3 Connect a 10kΩ resistor from each analog pin to the ground (GND) pin on the Ardui getting good readings from LDRs Need add battery for servos Added batt but readings erratic
