TUTORIAL TO BUILD SOLAR TRACKER FOR PANEL. JUST NEED 2 SERVOMOTORS, 4 PHOTOSENSITIVES RESISTANCE, AND A SERVO TESTER OR A RECEIVER, CUT THE WIRES OF POTENTIOMETER OF SERVO, ISOLATE AND REPLACE HIM, EXTEND THE 3 OTHER WIRES OUT AND CONNECT THE FIRST RESISTANCE TO THE 1ST AND 2ND WIRES, CONNECT THE SECOND RESISTANCE TO THE 2ND AND THE 3TH WIRES, HERE YOU HAVE BUILD YOUR SOLAR POTENTIOMETER, MAKE THE SAME TO 2ND, DO IT YOURSELF ALL THAT YOU THINK SUSCRIBE ON MY CHANNEL!
