1 × Arduino Nano A compact, breadboard-friendly microcontroller based on the ATmega328P. It's ideal for small projects, has USB connectivity, and offers 14 digital I/O pins, 8 analog inputs, and built-in serial communication.
1 × Ultrasonic Sensor A popular distance sensor that uses ultrasonic waves to measure the distance between the sensor and an object. It has TRIG and ECHO pins and can detect distances from 2cm to 400cm with good accuracy.
1 × 0.96" OLED Display (SH110, I2C) A 128x64 pixel monochrome display that communicates over I2C (2 wires only: SDA & SCL). It's perfect for showing text, numbers and simple graphics like bar graphs. Based on the SH1106 driver chip.
1 × Jumper Wires Flexible wires with male to female or male to male ends to make quick and easy connections between components on a breadboard or directly to headers.
1 × USB Cable (for Arduino Nano) Used to upload code from the Arduino IDE and provide power to the Arduino Nano during development or debugging.
