Solar Tracker Using Arduino And Servo Motor

It can also charge mobile phone.

Solar tracker using arduino and servo motor. 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. Arduino solar tracker with servomotor. So i ve made a solar tracker using an arduino and servo motor. Ldr 2 nos.

Similarly connect the gnd pin from the arduino to a second lower horizontal row of the breadboard. Extend the 5 volt and gnd rows to the upper horizontal rows of the breadboard respectively. 5 to 12 volt power supply. The circuit design of solar tracker is simple but setting up the system must be done carefully.

If you are simply trying this project for fun then a breadboard is perfect. Photovoltaic powers the solar tracker no external source needed. Two ldr s light dependent resistor are also connected to analog pins of the arduino. Interfacing dual axis solar tracker arduino project using ldr servo motors.

The sensors are connected in series with 10 k ohm resistors. In this project an arduino nano is used which works as a controlling unit. 3 two wires for supply and one wire for pwm to control its positions. Read servo motor control using arduino in the circuit two ldr light dependent resistors sensors are used to sense the light.

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. Tact switch button resistors 10k 3 nos. Before reading the post please check the video from my channel it gives 70 of idea about the project. 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.

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. Since ldr is an analogue sensor they are connected to the analog pins a0 and a1 of arduino. 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.

This solar tracker uses two ldrs to measure the light or the resistance of the ldr changes according to the light. The pwm inputs of two servos are given from digital pins 9 and 10 of arduino. The servo is controlled through one of the arduino s pwm outputs. The circuit diagram for the arduino based solar tracker using ldr servo motor is given below.
