We are almost done with assembling the car, at this point you can install Arduino module and DC motor controller to the frame. Most probably there will be a huge resistance, but you have to be gentle with it and use some power at the same time. Note that, there is a shape inside of the wheel hub so be sure to put it in the right place. Mount the nylon supporting wheel to the brass spacers with screws. Take the brass spacers and mount them to these holes with screws, so brass spacers are on the same side of the frame with motors. When you look at the end of the frame, there should be 4 small holes next to each other, looking like a square shape. Once the motors are on their place, it is time for the 3rd nylon supporting wheel. Please note that, each motor has a small "dot" on one side, and that dot should face inward so that when two motors are on place, these dots face each other. Take the motor, and mount it to the chassis frame with plastic brackets (2 for each), using screws and nuts.You can leave it like that, or to make it stronger just "knot" it or solder with longer, stronger cable/ jumper wires so that the connection is firm enough. Strip 2-4 cm of covering from both red and black cable. Strip a few centimetres of cable covering so you can see the cables inside it there should be 4/5 cables inside, but we are interested just in two cables, GND - black one, and Plus - Red one. Now take your old/spare USB cable, and cut it so there is around 20 cm of cable left. Prepare the main part of the chassis, 4 small plastic brackets which will mount motors on the chassis frame (2 for each), screws, brass spacers, nuts, motors, useless USB cable, and 4 cables/ jumper wires.Ĭonnect one wire to each pin of a motor, you can solder them but if you don't have soldering iron, just try to "knot" the cables to each pin. If you have a kit, most probably you also got the instructions with it, but just in case the steps can be found below: Male - male, and female - male jumper wiresĪrduCar - Arduino RC Car Bluetooth Controllerįirst of all, we will need to assembly the chassis of our car. Below, the list of the materials can be found: You may follow all of my instructions, but feel free to change some parts and be creative. So I have tried to make use of some old electronic things such as USB cable or power bank, that most of you may have somewhere at home. Moreover, provided instructions can be also used in different projects, so let's start!Īs a hobbyist, I didn't have many tools like soldering iron etc. The project covers the basics principles of creating such a car, with a minimalistic approach on materials, and explains the code in details. You may also ask, why Power bank? These days, those devices are becoming more and more affordable, in some cases, they are even cheaper than batteries, many of us have them at our own houses, they can be reused, and recharged anytime we want. Even though having some previous experience in those fields can be helpful, everyone should be able to finish this project without any problems. No prior programming, Arduino, or electronics experience needed. In this instruction, you will learn how to create an Arduino based RC car from a scratch. Last but not least, even though ArduCar is my own application written in Java, I have not provided the source code nor an explanation of it in this tutorial. This tutorial is heavily based on the technical explanation, however, in the second part of the tutorial, I explain the code written in Arduino IDE. First of all, this is an old article that I have published before on some technical websites related to microcontrollers, so you can treat this one just as a remastered version. I also had an RC car when I was a kid and always wanted to buy another one in my adulthood, so now when I have started learning to code, got an Arduino kit, it was the best time to make this childhood dream come true.īefore and if you proceed to the next part I want to add a few more things. As a technician, petrolhead and coding enthusiast, Arduino was always somewhere on my list. Another thing is a common myth that electronics are very difficult to understand and that we need at least an electronic engineer title to get started with it. Most of us here, write a lot of code and very rarely have any kind of interaction with electronics, which indeed run our codes. Electronics and Programming are not that Scary
