how to make automatic dual axis solar tracker using arduino
Homemade dual axis solar tracker Hello and welcome to the RC Invention projects. In this article, you will learn to make a dual axis solar tracker using Arduino, servo motor and LDR. Ingoing to use some this poject, we are use some light sensitive sensors like LDR to track the sunlight and direct the solar panel towards the sun that increase its efficiency Components required for this projects. 1. Arduino Uno or Nano. 2. servo motor (2nos). 3. LDR (Light Depending Resistor). 4. Resistor ( 1k to 10k ohm ) any one. 5. Solar panel . 6. PVC sheet . Circuit Diagram Arduino Code - 01 #include <Servo.h> // 180 horizontal MAX Servo horizontal; // horizontal servo int servoh = 180; // 90; // stand horizontal servo int servohLimitHigh = 180; int servohLimitLow = 65; // 65 degrees MAX Servo vertical; // vertical servo int servov = 45; // 90; // stand vertical servo int servovLimitHigh = 120; int servovLimitLow = 15; // LDR pin connections // name = analogpin; int ldrlt = 0;
