Component List

HC-SR04 Ultrasonic Sensor

• Description: The HC-SR04 is an ultrasonic sensor used for distance measurement. It emits an ultrasonic wave and measures the time it takes for the echo to return, allowing it to calculate the distance to an object.
• Pins: VCC, TRIG, ECHO, GND

Arduino UNO

• Description: The Arduino UNO is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins, 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header, and a reset button.
• Pins: UNUSED, IOREF, Reset, 3.3V, 5V, GND, Vin, A0, A1, A2, A3, A4, A5, SCL, SDA, AREF, D13, D12, D11, D10, D9, D8, D7, D6, D5, D4, D3, D2, D1, D0

Code Documentation

Arduino UNO Code

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

This code is a basic template for the Arduino UNO. The setup() function is where you initialize settings, and the loop() function runs continuously after the setup is complete. In this template, no specific functionality is implemented yet.
