How to Make CLAP Control Car || Using Arduino Uno

Hey Guys, welcome to my first instructables article. So guys today we are going to make a " Clap Control Car With Arduino " seems to be interesting Right?

Let me first tell you about the main working principle of this robot: This car uses a very working principle that are as follows:

~ When you CALP Once the car will go Forward.

~ When you CALP Twice the car will go Backward.

~ When you CALP Thrice the car will go Left

~ When you CALP for the Fourth Time the car will go Right.

It's very simple project but with the futuristic idea. if you have not understood its working principle then take a look at the whole tutorial you might then understand it...

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

~ So for making the chassis I am using a cardboard which is cut into the size of 10*14 cm.

~ Then we need a gear motor 4pcs.

~ We will stick the motor with the cardboard using hot glue gun.

~ We move into the wiring of the motors, the wiring will go in this way, we will solder the wires to the motors "+" and "-" terminals. As shown in the above image.

~ We will require a rubber wheel (4pcs) for the motor.

~ Put the rubber wheel in the gear motors. As shown in the above images.

~ Then our chassis is ready. lets move into the next step...

~ Now this step is very simple you need to attach the motor driver to Arduino Uno .Just motor driver according to the pin in the Arduino Uno.

~ So here we go, we need to put all the wires of the motor to the motor driver's Motor terminals.
Just put the first motor's wire to the motor driver M1 terminal. Then put the second motor's wire to the M2 terminal. Do the same with the rest of the motors.

You also follow the circuit diagram for doing the connection.

~ We will simply take three jumper wire and attach it to the sensor's pins:

+5v, GND & OUT.

~ Then we will fix the sound sensor to the Chassis with the help of Double Sided Tap.

~ Simply Connect the Sensor's:

OUT to D10

GND to Gnd

VCC to +5V

Following pin Into the Arduino.

~ We will that a Battery Holder and fix it to the chassis using Double Sided Tap.

Then Connect the GND wire of Holder to the Motor driver's Power GND Terminal. Then Connect the +5V wire to the Vcc or +5V Terminal of Motor driver.

Follow the Circuit Diagram for better understanding.

~ Now connect the usb cable to the Arduino Uno.

~ remove the OUT pin of the sensor for the successful uploading of the code.

Now Simply upload the following code:
