Ultrasonic Sensor
The ultrasonic sensor is a device used to detect objects and measure their distance away. It is connected to the Arduino board via 5 volts to 5 volts ground to ground, and two other wires to two digital inputs. The trig pin is declared as an output, while the echo pin is declared as an input. Variables are declared for calculations to determine the distance of the object.

Bluetooth is a wireless technology used to connect two devices. It is connected to the Arduino board via a Bluetooth module. The Bluetooth module is connected to the Arduino board via the TX and RX pins. Variables are declared for Bluetooth control. The Bluetooth module is then set up to communicate with the Arduino board.
Ultrasonic Sensor
The ultrasonic sensor is a device used to detect the presence of objects in its vicinity. It works by emitting a high-frequency sound wave, which is then reflected back to the sensor when it hits an object. The time it takes for the sound wave to return is then used to calculate the distance of the object from the sensor. This technology is used in a variety of applications, such as robotics, navigation, and security systems.
In order to use an ultrasonic sensor with an Arduino, the trigger pin must be set as an input, while the LED pin is set as an output. The trigger pin is then used to send out a signal, which is received by the echo pin. The time it takes for the signal to return is then used to calculate the distance of the object from the sensor. This is done using the equation: distance = speed of sound * duration / 2.
Bluetooth
Bluetooth is a wireless technology used to connect devices to each other. It is used in a variety of applications, such as streaming audio, transferring files, and controlling devices remotely.
In order to use Bluetooth with an Arduino, a serial communication connection must be established. This is done using the Serial.begin() command. Once the connection is established, data can be sent and received between the Arduino and a smartphone.
LED
LEDs are light-emitting diodes that can be used to create a variety of lighting effects. They are commonly used in a variety of applications, such as lighting displays, indicators, and indicators.
In order to use an LED with an Arduino, the LED pin must be set as an output. This is done using the pinMode() command. Once the pin is set as an output, the LED can be turned on and off using the digitalWrite() command.
Ultrasonic Sensor
The ultrasonic sensor is a device used to measure the distance between two objects. It works by emitting a sound wave and measuring the time it takes for the wave to bounce back. This time is then divided by two to get the distance from the starting point to the object. This data is then sent through the Bluetooth serial connection on Arduino EV, which can be done by using the serial one command.
Bluetooth Serial Connection
The Bluetooth serial connection is used to send data from the ultrasonic sensor to the Arduino EV. Once the data is sent, the Arduino will check to see if there is any data being sent and if the amount of data is above zero, it will read the data and store it in a variable. This variable, known as the LED data variable, is then used to determine whether the LED should be turned on or off. If the letter X is received, the LED state will be changed accordingly. After this, a delay of 100 milliseconds is used to give the sensors time to get ready for the next reading.
LED
The LED is used to indicate whether the ultrasonic sensor has detected an object. The LED state is determined by the LED data variable, which is set by the Bluetooth serial connection. If the LED state is set to one, the LED will be turned on, and if it is set to zero, the LED will be turned off. This allows the user to easily identify when an object has been detected by the ultrasonic sensor.
