Arduino Uno Coding

Welcome to the Arduino Uno Programming Showcase repository. This collection serves as a comprehensive archive of fundamental to intermediate projects using the Arduino Uno. It demonstrates capabilities ranging from basic LED manipulation to complex integrations with sensors, RTCs (Real Time Clocks), and LCDs.

📂 Repository Structure

The repository has different programming arudino projects focusing on specific components and programming concepts:

• LED Control Systems
  • Focus: Digital I/O, Analog Input, PWM.
  • Projects: Potentiometer-controlled brightness, Push-button toggle, and LED chaser patterns using combined inputs.
• 7-Segment Displays
  • Focus: Display logic, Arrays, Multiplexing.
  • Projects: Single digit counters, automatic counters, 2-digit push-button counters, and a 4-digit countdown timer with minutes/seconds.
• Environmental Sensors & LCDs
  • Focus: I2C Communication, Sensor Libraries, Data Visualization.
  • Projects: Basic LCD "Hello World", Temperature monitoring with LM35, and Humidity/Temperature tracking with DHT11.
• Advanced Timing & Alarms
  • Focus: Timekeeping, Relay Modules, Interrupts/State Machines.
  • Projects: Beep Quarter Timer, LCD Timer with DS1302/DS1307 RTC, and a fully functional Time Alarm system with relay activation.

🛠️ Hardware Requirements

To replicate these projects, you will need the following components:

• Microcontrollers: Arduino Uno R3 or Arduino Mega 2560
• Displays: 16x2 or 20x4 LCD (I2C), 7-Segment Displays (1-digit, 2-digit, 4-digit)
• Sensors: DHT11 (Humidity/Temp), LM35 (Temperature)
• Modules: DS1302/DS1307 RTC, Relay Module (1-channel)
• Basic Components: LEDs (Red/Green), Piezo Buzzer, Push Buttons, Potentiometers (10kΩ), Resistors (220Ω, 10kΩ), Breadboard, and Jumper Wires.

💻 Software & Libraries
