How to program Remote Control Car

How To Program Remote Control Car?

In this video, we will learn how to program remote control car by merging all our previous programs.

First, define motors. For controlling speed, define PW pins. As we are going to control the car using Bluetooth, we have to define a serial port. Now write the main program in the void loop as shown in the video. With the help of a conditional statement, you can write a program quickly.

After writing code, enable Bluetooth in a cell phone. Define new keys as per requirement. You can set forward, reverse, left, stop, right as per your comfort. Now interface all components as per video. Connect pins, motor driver, Arduino, motor, and Bluetooth module correctly.

Upload program on the device. Run and check the output by giving commands. Make necessary changes as required and again run your program. You will face some problems while doing any project, troubleshoot them, and keep changing your program.

So make a habit of debugging your program frequently. This way, you will able to write code efficiently and correctly. In the next lecture, we will fit all electronics in mechanical hardware. We will build our remote control car. The program will be the same in assembling a car.


The two terminals of the potentiometer are called “wiper” and “wiper”. The wiper is connected to the wiper terminal and the wiper terminal is connected to the shaft. The wiper terminal has a positive voltage and the wiper terminal has a negative voltage. When there is no rotation, both terminals are at zero volts and when there is rotation, one of them will be at zero volts while the other will have some voltage depending on how much it rotates.

Step 2: In the Arduino-IDE, compile the code below and hit upload, but first make sure the RX of the Arduino is detached from the TX of the Bluetooth Module (HC-05). Step 3: Download the app from the link provided below and install it on your Android device. Step 4: Use Bluetooth to connect your Android device to the HC-05.

  • #define TRIGGER_PIN A1 // Arduino pin to trigger pin on the ultrasonic sensor.
  • #define ECHO_PIN A2 // Arduino pin to echo pin on the ultrasonic sensor.
  • #define MAX_DISTANCE 250 // Maximum distance we want to ping for (in centimeters).
  • Maximum sensor distance is rated at 250cm.

  • The programming language used to program a remote control car is a bit tricky. There are many programming languages that can be used for this task, but it is important to choose the right one.
  • The programming language used for this task is C++. C++ is an object-oriented programming language that provides abstraction and encapsulation features.
