How to Make CLAP Control Car || Using Arduino Uno

Hey guys, welcome to my article tutorial. So guys, today we are going to make a "Clap Control Car With Arduino." It seems to be interesting, right?

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

• When you CLAP once, the car will go forward.
• When you CLAP twice, the car will go backward.
• When you CLAP thrice, the car will go left.
• When you CLAP for the Fourth Time, the car will go Right.

It's a very simple project but with a 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 :-)

Supplies

International:

Step 1: Making of the Chassis:

• So for making the chassis, I am using cardboard, which is cut into the size of 10*14 cm.
• Then we need 4 pcs. of gear motors.
• We will stick the motor to the cardboard using a hot glue gun.
• We move into the wiring of the motors; the wiring will go in this way, and we will solder the wires to the motors' "+" and "-" terminals. As shown in the above image.
• We will require a rubber wheel (4 pcs) for the motor.
• Put the rubber wheel in the gear motors. As shown in the above images.
• Then our chassis is ready. Let's move into the next step...

Step 2: Attach the Motor Driver With the Arduino Uno & Connecting the Motor Wires With the Motor Driver:

• Now this step is very simple; you need to attach the motor driver to Arduino Uno. Just the 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.

Step 3: Mounting the Sound Sensor Into the Chassis:

• We will simply take three jumper wires and attach them to the sensor's pins: +5V, GND & OUT.
• Then we will fix the sound sensor to the chassis with the help of double-sided tape.

Step 4: Connection of Sound Sensor to Arduino... & Battery Holder.

• Simply Connect the Sensor:

OUT to D10

GND to Gnd

VCC to +5V

Follow the pin into the Arduino.

• We will take a battery holder and fix it to the chassis using double-sided tape.

Then connect the GND wire of the holder to the motor driver's power GND terminal. Then connect the +5V wire to the Vcc or +5V terminal of the motor driver.

Follow the circuit diagram for better understanding.

Step 5: Time to Upload the Sketch:

• 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:
