Solar Tracker Using Arduino And Servo Motor

The pwm inputs of two servos are given from digital pins 9 and 10 of arduino.

Solar tracker using arduino and servo motor.

The circuit design of solar tracker is simple but setting up the system must be done carefully. Interfacing dual axis solar tracker arduino project using ldr servo motors. Ldr 2 nos. 5 to 12 volt power supply.

If you are going to be installing the solar tracker permanently then you may want to solder the resistors and ldrs together so that they cannot come loose. Four ldrs and four 100kω resistors are connected in a voltage divider fashion and the output is given to 4 analog input pins of arduino. Similarly connect the gnd pin from the arduino to a second lower horizontal row of the breadboard. This solar tracker system uses the arduino uno board a servomotor 2 ldrs and 2 resistors to rotate the solar panel towards the sun or a source of light.

Photovoltaic powers the solar tracker no external source needed. The sensors are connected in series with 10 k ohm resistors. Arduino solar tracker with servomotor. Two ldr s light dependent resistor are also connected to analog pins of the arduino.

This solar tracker uses two ldrs to measure the light or the resistance of the ldr changes according to the light. Before reading the post please check the video from my channel it gives 70 of idea about the project. Since ldr is an analogue sensor they are connected to the analog pins a0 and a1 of arduino. Connect 5volt pin from the arduino to the lower horizontal row of the breadboard.

The embedded software design the embedded software is the piece that will be embedded in the hardware arduino uno to control and monitor the solar tracker test bench. Extend the 5 volt and gnd rows to the upper horizontal rows of the breadboard respectively. The circuit diagram for the arduino based solar tracker using ldr servo motor is given below. In this project an arduino nano is used which works as a controlling unit.

To track the sun i used four ldc sensors and arduino compares the data from them to rotate the panel in the direction with the most sunlight using two dc motors one for each axis and motor driver. If you are simply trying this project for fun then a breadboard is perfect. Following are the list of components required to design a solar tracker. The used servo motors are controlled by the arduino uno board via 3 wire electrical cable as shown in fig.

3 two wires for supply and one wire for pwm to control its positions. It can also charge mobile phone. So i ve made a solar tracker using an arduino and servo motor. Tact switch button resistors 10k 3 nos.
