A solar tracker is a device that orients a payload toward the Sun. Payloads are usually solar panels, parabolic troughs, fresnel reflectors, lenses or the mirrors of a heliostat.
Manual mode: User can use IR remote to set the angle of motor, The change in angle will be displayed on the 16x2 lcd display.
Automatic mode: Using photoresistor or LDR the motor is set to the best position so that solar panel can get optimum output.
Circuit Diagram and screenshot of different modes are show in images ['capture_1.jpg', 'capture_2.jpg', 'capture_3.jpg']
