How to Make a TV Remote Control Robot Car

Hey Guys, welcome to my Instructables article. So guys today we are going to make a TV Remote Control Robot Car.

Project Information:

The project makes use of an IR receiver to receive the signal from our TV remote and then, as per the command received from the remote, the car performs the task. For example, when I click my remote’s forward button, the car moves in the forward direction and vice-versa.

Special thanks to PCBWay for sponsoring this project.

So let's get started with the project :-)

• Arduino nano: https://amzn.to/3JRkyqh

• IR Receiver kit: https://bit.ly/42JSsGg

• Chassis Project Sheet: https://bit.ly/3npGYaG

• L298N motor driver: https://amzn.to/3GxIMpq

• Bo Motor (4x): https://amzn.to/3i0EnBU

• Rubber wheel (4x): https://amzn.to/3i7n9mf

• Jumper wire: https://amzn.to/3Gycrid

• 18650 battery: https://amzn.to/3vunOBu

• 18650 battery holder: https://amzn.to/3hY0pFr

In this project, we are using a chassis sheet that is made of hard foam. This sheet can be used to make the chassis like solving a 3D puzzle. This step is very easy and simple, so just follow the image shared here and you can easily get your chassis ready for the project.

This can be done by using a PCB, I have many times used a custom-designed circuit board to give more professional touch. So I choose PCBWay to design and order the custom-designed PCB for this project.

Follow the Steps:

1. Solder all the components to the Moto Driver PCB.
2. Now Mount the Moto Driver to Arduino and using double tape mount it to the chassis.
3. Then make the connection of the Motor to the Moto Driver as shown in image.
4. Then connect the jumper wire with the Moto Driver pin out and IR Receiver.
5. Now Mount the IR Sensor to the sensor place holder.
6. Then attach the battery holder to the chassis.
7. Now connect the battery holder pin out to moto driver power pin.

Now we are done with the circuit part.

Upload the code and don't forget to include the libraries.
