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.

Interfacing dual axis solar tracker arduino project using ldr servo motors. 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. If you are simply trying this project for fun then a breadboard is perfect. The circuit diagram for the arduino based solar tracker using ldr servo motor is given below.

Connect 5volt pin from the arduino to the lower horizontal row of the breadboard. 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. It can also charge mobile phone. So i ve made a solar tracker using an arduino and servo motor.

The pwm inputs of two servos are given from digital pins 9 and 10 of arduino. The sensors are connected in series with 10 k ohm resistors. Photovoltaic powers the solar tracker no external source needed. Ldr 2 nos.

Similarly connect the gnd pin from the arduino to a second lower horizontal row of the breadboard. 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. 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. 5 to 12 volt power supply.

The servo is controlled through one of the arduino s pwm outputs. Since ldr is an analogue sensor they are connected to the analog pins a0 and a1 of arduino. The circuit design of solar tracker is simple but setting up the system must be done carefully. 3 two wires for supply and one wire for pwm to control its positions.

Two ldr s light dependent resistor are also connected to analog pins of the arduino. Following are the list of components required to design a solar tracker. 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. Arduino solar tracker with servomotor.

Tact switch button resistors 10k 3 nos. The used servo motors are controlled by the arduino uno board via 3 wire electrical cable as shown in fig. This solar tracker uses two ldrs to measure the light or the resistance of the ldr changes according to the light. Extend the 5 volt and gnd rows to the upper horizontal rows of the breadboard respectively.
