Key Features
- ATmega328P Microcontroller: Industry-standard 8-bit AVR processor running at 16 MHz for reliable, real-time performance across thousands of compatible projects.
- 14 Digital I/O Pins: Including 6 pins with PWM output capability for motor control, LED dimming, servo driving, and signal generation.
- 6 Analog Input Channels: 10-bit ADC resolution for reading sensors such as temperature, light, humidity, potentiometers, and more.
- USB Plug-and-Play Programming: Connect via standard Type-B USB cable, upload sketches directly from the Arduino IDE — no external programmer required.
- Onboard Voltage Regulator: Accepts 7–12V DC input via barrel jack or Vin pin, with built-in 5V and 3.3V regulated outputs to power external components.
- Full Shield Compatibility: Standard Arduino Uno R3 header layout ensures compatibility with hundreds of expansion shields — motor drivers, Ethernet, Wi-Fi, relay boards, LCD displays, and more.
- ICSP Header: In-Circuit Serial Programming header for advanced users who want to program the microcontroller directly or update the bootloader.
- Reset Button: Onboard tactile reset button for quick program restarts during development and debugging.
- Built-in LED: Onboard LED connected to digital pin 13 for instant testing and debugging without any external wiring.
- Cross-Platform Support: Works seamlessly on Windows, macOS, and Linux with the free Arduino IDE software.
Why Choose This?
- 100% tested and verified compatible board — works identically to the original Arduino Uno R3 with all libraries, shields, and code examples
- Affordable price point without compromising on build quality, component reliability, or performance
- 2–3 day shipping from our Bengaluru warehouse to most locations across India
- Expert technical support included — our engineers help you with setup, coding, and troubleshooting
- Backed by a massive global community with thousands of free tutorials, projects, and code libraries
- Perfect stepping stone into embedded systems, IoT, robotics, and automation
Project Ideas
- Home Automation System: Control lights, fans, appliances, and door locks remotely using relay modules, Bluetooth (HC-05), or Wi-Fi (ESP8266) shields connected to your Uno.
- Weather Station: Read temperature (DHT11/DHT22), humidity, barometric pressure (BMP180), and air quality sensors, then display real-time data on an LCD or log it to an SD card.
- Line-Following Robot: Build an autonomous robot using IR sensors and motor driver shields — a classic robotics project ideal for competitions and learning PID control.
- Smart Irrigation System: Monitor soil moisture levels and automatically control water pumps to keep your garden or farm optimally watered, reducing water waste.
- LED Matrix & Display Projects: Drive LED
