Have you ever wondered how a robot can follow a light source? It's an exciting project that lets you explore the basics of robotics and electronics. In this blog, we'll guide you through creating your very own light seeking bot. This project is perfect for kids under 15 who want to dive into the fascinating world of robotics and learn how these intelligent machines work.

This project is suitable for kids aged 10 to 15 years old. It introduces basic concepts of robotics, electronics, and programming in a fun and engaging way. Younger children might need some adult supervision and assistance, especially with using tools and handling electronic components.

Getting Started with the DIY Kit

 Materials You Will Need

Before you start building, gather the following materials:

- A robot chassis (the body of your robot)

- Two DC motors with wheels

- A motor driver board (like L298N)

- An Arduino microcontroller

- Light sensors (photoresistors or photodiodes)

- A battery pack

- Jumper wires

Assembling Your Robot

Assembling a light seeking robot involves attaching the motors and wheels to the chassis, connecting the motor driver and Arduino microcontroller, and fixing the light sensors in place. Ensure all connections are secure and power off the components while making connections. Finally, upload a simple Arduino program to control the motors based on the sensor inputs.

Enhancing the Learning Experience

Building a light seeking robot is just the beginning. Here are some ideas to make the experience even more exciting:

Experiment with Different Light Sources &  Add More Features

Try using different light sources like flashlights, LED lamps, or natural sunlight. Observe how your robot responds to these changes and adjust the sensor sensitivity if needed.

Enhance your robot by adding more sensors or components. For example, you can add more light sensors to improve detection accuracy or a buzzer to alert when the robot finds the light source.


Building a light seeking robot is a fun and educational project that introduces kids to the exciting world of robotics. By following these simple steps, you can create a smart robot that can navigate its way towards a light source all by itself. So, gather your materials, follow the instructions, and enjoy the thrill of watching your very own robot in action!

Remember, the journey of building and learning is just as important as the final product. Happy building!

Frequently Asked Question's

What is a light seeking robot?

Ans: A light seeking robot is an autonomous robot that can detect and move towards a light source using sensors, typically photoresistors or photodiodes.

Do I need to know programming to build this robot?

Ans: Basic knowledge of programming is helpful, but the provided code is simple and easy to understand. You can also find many tutorials online.

What should I do if my robot isn't seeking the light correctly?

Ans: Check the sensor connections and ensure they are correctly placed. Make sure the sensors are calibrated properly and adjust the sensitivity in the code if needed.

Can I use different sensors?

Ans: Yes, you can experiment with different types of sensors like phototransistors or light-dependent resistors (LDRs) to see how they affect the robot's performance.

How long does it take to build a light seeking robot?

Ans: The time it takes can vary depending on your experience level and the complexity of the robot. Generally, it can take a few hours to a day to assemble and program the robot.

Can I build this robot with friends or as a school project?

Ans: Absolutely! Building a light seeking robot is a great group activity and can be an excellent project for school science fairs or robotics clubs.
