This is an interactive project in which we are making an IR control Robot using IR remote interfacing with Arduino uno.
This remote controlled car can be moved around using practically any kind of remote such as TV, AC etc.
It makes use of the fact that the remote emits IR (infrared).

Finding Hexadecimal Values of Remote Keys
Here I have obtained the values of the front, back, left, right and middle keys which are
These values of these buttons are mapped to move front, move back, move left, move right and brake respectively.
Arduino L293D Motor Driver Module
Pin 4 -> Pin IN1
Pin 5 -> Pin MTR
Pin 6 -> Pin IN2
Pin 7 -> Pin MTR
Pin +5V -> Pin +5V
Pin GND -> Pin GND
Now integrate everything i.e. both the IR receiver part and L293D part.
Basically you can first make the IR connections, find hexadecimal value and without disturbing the IR connections, make the L293D connections and interface the motors with Arduino.
Welcome to the Arduino Based Remote Controlled Car which consists of IR Receiver. The basic working principle of the project depends upon the IR Sensor which is being described here. When the IR receiver does not receive a signal, the potential at the inverting input goes higher than that non-inverting input of the comparator IC (LM339). Thus the output of the comparator goes low, but the LED does not glow. When the IR receiver module receives signal to the potential at the inverting input goes low. Thus the output of the comparator (LM 339) goes high and the LED starts glowing.
Upload the code given in rc_car.ino into the Arduino (provided both IR and L293D connections have been made).
The code just like the previous schematic is just an integration of remote and motor test codes i.e. the Arduino first now checks the remote key which you have pressed by obtaining its hexadecimal value , checks what function has been mapped to that value and
performs the required function through L293D Check if the bot moves as required or not.
Go to this repository to download the code and schematics. Click on the "Clone or Download" button (green in color on the right side) and select "Download ZIP" to download the zip file. Now extract the contents on your computer to get the code and schematics (in the schematics folder).
During motor connections, you may quiet watch the connections of motors and check the proper direction of the motors in which the motor rotate so it is easy to rotate your robot.
You may also use the l293d motor driver module it is easy to use and connections and use two batteries 1 12v for motors and other 9v for arduino uno.
And you will easily access the robot and you may also change some codes of motors that in which direction you may connect you will see and change the changes in codes
