Solar Tracker Using Arduino And Servo Motor

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.

Solar tracker using arduino and servo motor.

Before reading the post please check the video from my channel it gives 70 of idea about the project. Arduino solar tracker with servomotor. Connect 5volt pin from the arduino to the lower horizontal row of the breadboard. The servo is controlled through one of the arduino s pwm outputs.

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. If you are simply trying this project for fun then a breadboard is perfect. So i ve made a solar tracker using an arduino and servo motor. The sensors are connected in series with 10 k ohm resistors.

Read servo motor control using arduino in the circuit two ldr light dependent resistors sensors are used to sense the light. Similarly connect the gnd pin from the arduino to a second lower horizontal row of the breadboard. Following are the list of components required to design a solar tracker. In this project an arduino nano is used which works as a controlling unit.

The pwm inputs of two servos are given from digital pins 9 and 10 of arduino. Photovoltaic powers the solar tracker no external source needed. The circuit diagram for the arduino based solar tracker using ldr servo motor is given below. 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.

It can also charge mobile phone. Interfacing dual axis solar tracker arduino project using ldr servo motors. Tact switch button resistors 10k 3 nos. A dummy solar plate is attached in parallel to the axis of servo motor and both the sensors are kept on the dummy solar plate as shown in the figure below.

Ldr 2 nos. 5 to 12 volt power supply. Extend the 5 volt and gnd rows to the upper horizontal rows of the breadboard respectively. This solar tracker uses two ldrs to measure the light or the resistance of the ldr changes according to the light.

The circuit design of solar tracker is simple but setting up the system must be done carefully. 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. Since ldr is an analogue sensor they are connected to the analog pins a0 and a1 of arduino. The used servo motors are controlled by the arduino uno board via 3 wire electrical cable as shown in fig.
