As we all know, Arduino is a micro controller that acts according to the at-mega 328. There are 6 Pwn outputs and 16MHZ resonators. we can perform different types of circuits using the Arduino board. Here I utilize it to design and made a toy car using Arduino Uno. If you are interested in building circuits, hope this will be a good one for you. I'll explain step by step how to do it. Let's get started

| ARDUINO UNO BLUETOOTH CONTROLLED TOY CAR |
👉Before start, you need the following items
Apparatus
- Arduino Uno board
 |
| Arduino Uno board |
- Bluetooth module (hc-06)
 |
| Bluetooth module (hc-06) |
- dc Motor driver(L298N)
 |
| dc Motor driver |
- jumper wires
 |
| jumper wires |
- two phone battery
 |
| phone battery |
- dc motor with gear
 |

ARDUINO CODE
* THIS CODE WORKS FOR L298N MOTOR DRIVER. IF YOU UTILIZE L293D MOTOR DRIVE cannot USE THIS CODE.

void mpower(int motor, int rotation, int spd)
else if (motor == 2)
else
if (rotation == 0)
else if (rotation == 1)
else if (rotation == -1)
analogWrite(pwm, spd);
}
void loop()
if (val == '2')
if (val == '3')
if (val == '4')
if (val == 'x')
}
if (val == 'f')
if (val == 'a')
if (val == 'b')
}
NOTE
IF YOU UTILIZE PHONE BATTERY FOR DC PROVIDE UP TO 1500mAh BATTERY AND CONNECT TWO PHONE BATTERY IN SERIES
